cystic degeneration of fibroid ct

The cystic spaces have markedly increased SI on T2-weighted images and do not enhance on contrast-enhanced imaging . An icon used to represent a menu that can be toggled by interacting with this icon. When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration. B, Sagittal T1-weighted image with fat saturation shows diffuse enhancement after administration of IV contrast agent. Jun 26, 2016. 3A —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. cystic degeneration of the fibroid (arrows). Cystic degeneration is evidenced by internal areas of T2 hyperintensity (fluid signal) with a lack of contrast enhancement . Ultrasonography (USG) and CT showed a large mass abutting the uterus extending into the abdomen. 28, No. Rupture of degenerated cystic fibroid is rare, but it should be included in the differential diagnosis when encountering patients with a cystic tumor and massive ascites. Uterine STUMPs have been only sporadically described in the imaging literature given their rareness. 5), as well as mitotically active leiomyomas, are very rare; hence, reports of their imaging appearance are scarce. AB - Uterine fibroids are the most common benign uterine neoplasms, occurring in 20% to 30% of women of reproductive age. 26, No. Typical appearance of fibroid uterus on CT. 24: A. No matter how severe the pain is, it is not life threatening. One of the four patients with presumed stage I STUMP who was immediately surgically staged was found to have an omental implant. The process of fibroid degeneration may sometimes cause pain in the pelvic region. Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. One case report [38] of an atypical leiomyoma arising from the vaginal fornix was well defined, moderately T2 intense, and homogeneously enhanced. Patient underwent … Computed tomography. 4B —45-year-old woman with symptomatic fibroids who underwent MRI for preoperative planning. Though fibroid degeneration does decrease the size of fibroids, it cannot manage them long-term — a degenerated fibroid is likely to expand and degenerate again. 3B —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. These atypical smooth muscle cells have abundant eosinophilic cytoplasm, irregular nuclear shapes, and multinucleation. MRI was interpreted as worrisome for leiomyosarcoma; therefore, she instead underwent hysterectomy, performed by gynecologic oncologist, which confirmed MRI diagnosis. An early study on MRI of uterine sarcomas (n = 22) [41] concluded that the most common appearance was a large heterogeneous mass. Occasionally, cells have further chromatin condensation and fragmentation, resembling atypical mitotic figures. Parasitic leiomyomas are attached to the pelvic peritoneum and are presumed to originate from a pedunculated subserosal leiomyoma that became vascularized by the adjacent peritoneum, losing its attachment to the uterus and its blood supply, but are also histologically benign. WebMD's pictures show you all about fibroid symptoms, treatments, and the causes. Cystic degeneration is evidenced by internal areas of T2 hyperintensity (fluid signal) with a lack of contrast enhancement . Generally, the ultrasonic appearance of uterine fibroids is typical, and diagnosis is uncomplicated. On the basis of these findings, subserosal myoma or an intra-ligamentary fibroid with. Internal echo-poor foci suggest degeneration [25], and a hyperechoic echo pattern may suggest a lipoleiomyoma [26]. Results were read as fibroids, but at pathologic examination, large mass was found to be smooth muscle tumors of uncertain malignant potential (STUMP). 2B —53-year-old woman with indeterminate mass on ultrasound. B A C vol25_no5_jum_online.q 4/14/06 10:26 AM Page 673. characteristic of a rim of myometrium usually seen in a cystic fibroid.5 The cesarean delivery surgical report stated that the 18-cm pedunculat-ed cystic mass arose from the posterior surface of the body of the uterus and extended inferiorly in the cul-de-sac. B, Coronal T2-weighted scan shows that mass is intermediate signal intensity. Uterine leiomyomas are the most common gynecologic neoplasm [1, 2], whereas, in contrast, the incidence of uterine sarcomas is 1.7 in 100,000 women, with the vast majority being leiomyosarcomas [3]. The histopathology result confirmed hyaline cystic degeneration of uterine fibroids. In non –pregnant it may appear so … [7], who conducted a review of 1332 patients who underwent surgery for presumed leiomyoma and concluded that, “The incidence of sarcoma among patients having surgery for ‘rapidly growing' leiomyoma (0.27%) or among those who met published criteria for rapid growth (0%) does not substantiate the concept of increased risk of sarcoma in these women.” Thus, the diagnosis of a variant cannot be made with certainty until a pathologist thoroughly evaluates the surgically removed fibroid (see the Pathologic Features of Leiomyoma Variants section later in this article). In terms of treatment, if a clinician is informed that a fibroid or uterine mass looks unusual on imaging studies, then this can influence how the tumor is treated. 6, International Journal of Surgery Case Reports, Vol. A pelvic mass was felt, and computed tomography demonstrated a 13-cm hypodense multilocular cystic mass … In addition, studies have shown that cellular leiomyomas can significantly decrease in size after gonadotropin-releasing hormone therapy compared with degenerated leiomyomas [36]. Fibroids are noncancerous tumors that grow on or in the muscular walls of the uterus. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm mimicking malignant ovarian tumor. CT is not the primary modality in the diagnosis of fibroid Dec 11, 2018. of degeneration include hyaline, myxoid, cystic and red degeneration. 3C —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. Fig. 8B —49-year-old woman with history of fibroids referred for MRI for before uterine fibroid embolization. In between, there are several leiomyoma variants, such as mitotically active, cellular, and atypical leiomyomas, as well as smooth muscle tumors of uncertain malignant potential (STUMP). Decreased blood supply to the fibroids may influence liquefaction of hyalinized areas that are seen as cystic changes on the … View The diagnosis of a uterine fibroid with cystic degeneration was made. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm. 4A —45-year-old woman with symptomatic fibroids who underwent MRI for preoperative planning. [13] state, “The ideal criteria for follow-up remain elusive. Cystic degeneration is evidenced by internal areas of T2 hyperintensity (fluid signal) with a lack of contrast enhancement [30]. Atypical leiomyomas (Fig. Discover the world's research On ultrasound, the detection of hypervascularity in a large solitary uterine mass can identify suspicious masses, such as a leiomyosarcoma [27]. Despite this, because of their rarity, there are no well-defined clinical guidelines for the clinician to follow. When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration. Background/aims: The differential diagnosis of cystic uterine tumors includes fibroids showing cystic degeneration, cystic adenomyomas, congenital cysts, and developmental anomalies. 4, International Journal of Paleopathology, Vol. Fortunately, most of these variants are rare and have a benign natural history, given currently there are no significant series to establish definitive clinical or imaging findings that can reliably distinguish among them. Precise knowledge of the histopathologic backgrounds of degeneration and the clinical course helps u… They were hypointense on T1-weighted scans (not shown). MRI provides more accurate morphological soft-tissue detail when compared with computed tomography (CT), and has a useful pre-operative role in some cases, particularly in monitoring fibroid degeneration and identifying sarcomatous changes. the degeneration – hyaline, cystic, myxoid, red degeneration and dystrophic. Fig. Enter your email address below and we will send you the reset instructions. It can occur in pregnancy and non-pregnant state in the reproductive age. Background: Uterine fibroid is one of the most common pelvic neoplasms. Fibroids are responsive to hormones (e.g. [9] reviewed 127 patients representing the pathologic spectrum, from uterine leiomyomas to leiomyosarcomas, using World Health Organization and Stanford criteria. It is unclear whether uterine fibroid embolization treats a STUMP or atypical myoma, but if the fibroid could be a leiomyosarcoma, then uterine fibroid embolization will not be effective and it will continue to grow [21]. Heterogeneous enhancement, although subjective to some degree, was more frequent in the malignant than in the benign group, and perfusion imaging was not useful for either group; because the uncertain malignant potential tumors were grouped with the malignant tumors, the imaging differences between these groups remain unclear. 1B —38-year-old woman with symptomatic leiomyomas. On T1-weighted images, there was high signal intensity indicative of hemorrhagic necrosis in the sarcomas, not seen in the other lesions (Fig. An intramural fibroid is a noncancerous tumor that grows between the muscles of the uterus, typically discovered during a routing pelvic exam. Nov 1, 1990. Their typical appearances at magnetic resonance (MR) imaging have been well established (,3,,4). Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. C, Axial T1 fat-suppressed IV contrast-enhanced scan shows homogeneous enhancement. C, Axial T1-weighted fat-suppressed IV contrast-enhanced scan shows areas of nonenhancement that correspond to foci of hemorrhage, consistent with hemorrhagic necrosis, commonly seen in leiomyosarcomas. Other studies also support that both mitotically active and cellular leiomyomas rarely recur. On ultrasound, the classic appearance of an ordinary (nondegenerated) leiomyoma is a round or oval circumscribed hypoechoic solid mass, often with associated posterior shadowing due to calcifications or interface of the margins of the leiomyoma with the normal myometrium. [14], have reported higher recurrence rates (12.5%), albeit with a smaller sample size (n = 16). 29, No. Mass was predominantly cystic with septations. [12] described 51 atypical leiomyomas of the uterus: one of 34 patients undergoing hysterectomy had recurrent disease in the retroperitoneum, two of 17 patients initially treated by myomectomy were found to have residual atypical leiomyoma in a subsequent hysterectomy, and a third patient underwent a second myomectomy for atypical leiomyoma (4/34; 12%). In contrast, studies in the literature suggest that atypical leiomyomas and uterine STUMPs may have a greater risk of recurrence. Fig. stimulated by estrogens). Moreover, most of these STUMPS with a malignant potential are p53 and p16 positive. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm. 4, American Journal of Roentgenology, Vol. The tumor is rich in vasculature of various calibers and types, including muscle-rich arteries, arterioles, and veins. Affiliations. The 43 years, patient presented with lump abdomen with heavy periods and anemia. non-degenerated fibroids and calcification appear as low to intermediate. At laparotomy a huge cyst of 41cm×38cm originating from the anterior uterine wall with multiple adhesions, cystic fluid measured about 8.2litres. Leiomyomas with hyaline or calcific degeneration are generally low in SI, whereas those with cystic degeneration are generally very high in SI. The utility of PET/CT to differentiate ordinary leiomyomas, leiomyomas variants, and leiomyosarcomas remains limited because ordinary leiomyomas can take up FDG on PET [45]. Out of these, hyaline degeneration is common occurring in about 60% of cases whereas cystic degeneration is rare in about 4%. 5B —39-year-old woman with pelvic pain and presumed ordinary leiomyoma after receiving therapy with leuprolide acetate (Lupron, Abbvie). B, Sagittal T2-weighted fat-suppressed scan shows amorphous moderate-signal-intensity tissue that has poorly defined margins with myometrium. MRI showed large multiseptated cystic mass 21 × 16 cm × 12 cm in the right. Degenerated leiomyomas have a variable appearance on T2WI. Cystic degeneration may be considered an extreme sequela of edema and is observed in about 4% of leiomyomas (, 1). This is concerning for clinicians and radiologists alike, who both struggle with the same question: when should I refer a patient for MRI? This antiangiogenic mechanism is likely to be responsible for the cystic myoma degeneration in our case 4. Intraperitoneal haemorrhage secondary to perforation of uterine fibroid after cystic degeneration. Fig. This article reviews current approaches to the management of uterine fibroids, soft-tissue detail when compared with computed tomography (CT), and has a useful. 8), and on T2-weighted images, the sarcomas were intermediate to high signal intenstiy. Patient risk factors—such as increasing age, race (African American), long-term (≥ 5 years) Tamoxifen use, pelvic radiation, and certain high-risk conditions (i.e., hereditary leiomyomatosis and renal cell carcinoma syndrome and hereditary childhood retinoblastoma)—can and should be taken into account, with the caveat that they too are insufficiently studied because of the overall low incidence of uterine sarcomas. Of these, 8 corresponded to the diagnosis of a non-fibroid uterine cystic enlargement, and 21 to that of a fibroid with cystic degeneration. As Guntupalli et al. The two leiomyoma variants that require clinical and imaging surveillance after myomectomy are atypical leiomyoma and STUMP. If a leiomyoma undergoes myxoid degeneration, then hypocellularity and a myxoid matrix without nuclear atypia or other features of malignancy is seen. 189, No. For example, in one of the largest series on this variant, Ly et al. For patients who have only undergone a myomectomy and found to have an atypical leiomyoma and wish to retain their uterus, annual pelvic ultrasound or, preferably, MRI should be incorporated into surveillance of the uterus. In a way, fibroids degeneration can be seen as natural uterine artery embolization. Nihar Ranjan Bhoi et al 60 JSAFOMS Large Cystic Degeneration of Subserosal Fibroid and Diagnostic Dilemma 1Nihar Ranjan Bhoi, 2Chintamani Mohanta, 3Sudha Agrawal, 4Amulya Kumar Panda ABSTRACT Introduction: Leiomyoma of the uterus is the most common tumor arising from uterine smooth muscle. 22, No. None of six mitotically active leiomyomas and none of 17 cellular leiomyomas recurred; however, three of 31 (10%) atypical leiomyomas and three of 14 (21%) STUMPs with clinical follow-up recurred (with one of the latter having died of meta-static disease). The purpose of this article is to review the clinical, imaging, and pathologic features of leiomyoma variants. 18, American Journal of Roentgenology, Vol. A, Axial T2-weighted scan shows isolated well-defined moderate-signal mass. 6D —45-year-old woman who underwent MRI to evaluate size of uterine fibroids. However, they can be difficult for a radiologist to distinguish from an aggressive tumor, particularly the ones involving the peritoneal cavity and lungs; the differential diagnosis should be considered in a premenopausal woman with a history of fibroids [35]. How often suspicious imaging or clinical features actually turn out to be just an ordinary myoma is not known, and how often even the most experienced radiologist is going to be right is unknown. Fibroid growth is a balance between mitosis, which produces more fibroid cells, and necrosis or apoptosis, which kills fibroid cells. Int J Gynecol Endsc 2017;1(1):46-49. On MRI, a nondegenerated leiomyoma characteristically is T1 isointense relative to the surrounding myometrium and homogeneously T2 hypointense with enhancement after the administration of IV contrast agent (Fig. 31, No. Linear signal void along posterior fundus represents prior myomectomy changes after removal of conventional fibroid. Hyaline cystic degenerations of the uterine fibroids may be rare but not uncommon. cystic degeneration: [ de-gen″ĕ-ra´shun ] deterioration; change from a higher to a lower form, especially change of tissue to a lower or less functionally active form. Methods: The incidence, clinical presentation and accuracy in preoperative diagnosis of cystic uterine tumors were studied in a university hospital population over a 6-year period. In summary, although certain MRI features indicate different types of myoma degeneration, there are no definitive imaging findings that reliably differentiate ordinary leiomyomas from leiomyoma variants. 8C —49-year-old woman with history of fibroids referred for MRI for before uterine fibroid embolization. the degeneration – hyaline, cystic, myxoid, red degeneration and dystrophic. As fibroids enlarge, they may outgrow blood supply and they may degenerate. Cellular leiomyomas in one series (n = 44) [36] had lower T2 signal intensity and were markedly enhanced compared with degenerated ordinary leiomyomas (Fig. 7, Best Practice & Research Clinical Obstetrics & Gynaecology, Vol. It is rare for this condition to manifest as acute symptoms necessitating emergency surgical intervention. In the present case, cystic degeneration with intervening septations in an adnexal mass raised the suspicion of ovarian neoplasm as the ovaries were not seen as separate from the lesion. Results were read as fibroids, but at pathologic examination, large mass was found to be smooth muscle tumors of uncertain malignant potential (STUMP). The 43 years, patient presented with lump abdomen with heavy periods and anemia. Fig. Also recently, the negative effect of leiomyoma morcellation devices on the survival of patients who are found to have malignant instead of benign uterine masses has received attention, not only in the medical literature but also in the lay press [6]. Fibroid degeneration takes place when the fibroid has been increasing in size over a number of years, and its blood supply is no longer adequate to support the center of the tumor. There is now a published series of six patients with STUMPs treated with power morcellation techniques [16]. Myxoid degeneration is a rare type of leiomyoma degeneration. As already mentioned, hyaline degeneration often precedes cystic degeneration. The patient underwent a laparotomy. Imaging Features of Postoperative Complications After Spinal Surgery and Instrumentation, Review. Fever in addition to other symptoms. 4). C, Typical histologic specimen of ordinary leiomyoma shows fascicles or bundles of elongated spindle cells with eosinophilic cytoplasm and centrally located cigar-shaped nucleus with interstitial and rich vasculature. Fig. Table 1 summarizes ordinary leiomyomas, including their various forms of degeneration, and their main variants. Another article [39] reported that uterine sarcomas (five leiomyosarcomas and two endometrial stromal sarcomas) and two cellular leiomyomas exhibited high signal intensity on DWI sequences, whereas ordinary leiomyomas (including degenerated ones) showed low signal intensity; however, as acknowledged, a statistical analysis was not performed because of the small sample size. Nonetheless, the bottom line is that, at the present time, the diagnosis of a leiomyoma variant cannot be made with certainty until a pathologist, guided by recently updated 2014 World Health Organization criteria [8], thoroughly examines the specimen. A, Sagittal T2-weighted scan shows difficult-to-see moderate-signal-intensity fundal lesion that is fairly well defined given that its signal is almost isointense with myometrium. Hemorrhagic (carneous) degeneration typically shows high signal intensity on T1-weighted scans and moderate to high signal intensity on T2-weighted scans; there can also be a hyperintense rim on T1-weighted scans and a very hypointense rim on T2-weighted scans [ 31 ]. Fig. Uterine leiomyomas (also known as myomas or fibroids) and leiomyosarcomas are at opposite ends of the pathologic spectrum of uterine smooth muscle tumors. The typical appearance of a … Ultrasound is the first-line imaging modality because it is a cost-effective portable real-time examination that provides good anatomic detail without radiation. Large or small cystic spaces develop in the edematous, acellular center (, 1,, 5,, 6). The available evidence suggests that hypointense T1 signal, moderate T2 signal intensity, and high signal intensity on DWI are not typical findings of ordinary leiomyomas, and thus, if present, especially in combination, might raise the possibility of a leiomyoma variant. Fig. Large fibroids often undergo hyaline, cystic, and at times, red degeneration.

[11] reported the largest single-institution series of women who were treated for cellular leiomyomas, and only two of 99 patients (2%) had recurrent disease, one 43 months after an abdominal myomectomy and the other 120 months after a vaginal hysterectomy for multiple cellular leiomyomas (with benign metastasizing leiomyomas to the lungs). Uterine fibroids, also known as leiomyomas, are the commonest uterine neoplasms. Degeneration, involving cell death, occurs inside the fibroid, and calcification, where calcium is deposited in the fibroid tissue, may be seen on an ultrasound scan. Uterine fibroid vascular supply from … Epidemiology This type of degeneration is thought to represent ~4% of all types of degeneration. Ultrasound and CT -Scan suggested “Ovarian Malignancy”!! 7, No. There are no clinical findings that reliably differentiate ordinary leiomyomas from leiomyoma variants and leiomyosarcomas. Some familial and sporadic syndromes with association of multiple cutaneous and uterine leiomyomas have been described [48]. Up to 75% of hysterectomy specimens harbor leiomyomas, with multiple leiomyomas seen in most cases. 3, Journal of Computer Assisted Tomography, Vol. Benign uterine leiomyomas (fibroids) are the most common pelvic. The type of degenerative change depends on the degree and rapidity of the onset of the vascular insufficiency. Uterine leiomyomas and leiomyosarcomas are at opposite ends of the pathologic spectrum of uterine smooth muscle tumors. The ultrasonographic and contrast-enhanced computed tomographic findings of this case were characteristic of ovarian neoplasm. By using the body’s natural pathways, the Interventional Radiologist will thread a tiny catheter through your arteries straight to the fibroid(s). D, Representative histologic specimen of uterine STUMP shows marked cellularity and cytologic atypia (but mitotic count < 10/10 high-power fields). 71, No. If future MRI research cannot improve diagnostic imaging accuracy, perhaps there is a potential role for nuclear medicine imaging. Fatty degeneration or lipoleiomyoma has signal intensity consistent with fat on MRI [32] (Fig. STUMP is diagnosed when atypical histologic features are found that range between leiomyoma and leiomyosarcoma [8]. This term is related but not. Fig. Int J Gynecol Endsc 2017;1(1):46-49. In contrast to ordinary leiomyomas, leiomyoma variants are neither well studied nor understood from an imaging perspective. 1, No. In one study comparing MRI and PET [23], nonbenign leiomyomas had significantly higher standardized uptake values than did benign ones, but there was overlap; ordinary leiomyomas versus leiomyoma variants were not separately analyzed and fell into both groups. Subserous fibroids—these fibroids grow predominantly outside the uterus and bulge. C, Oblique sagittal IV contrast-enhanced scan shows that mass exhibits laminated pattern of enhancement consistent with myxoid leiomyoma. Ultrasound diagnosis was ovarian cyst. Fig. Ultrasonography (USG) and CT showed a large mass abutting the uterus extending into the abdomen. Key teaching point, in this case, is that cystic degeneration of fibroids can look very large and alarming and raise the concern for a malignant mass. In one article [22] looking at the MRI accuracy of diagnosing leiomyoma subtypes (n = 45), there was 95% sensitivity and 72% specificity for nondegenerated leiomyomas, 80% sensitivity and 98% specificity for cystic degeneration, 100% sensitivity and 86% specificity for hemorrhagic degeneration but only a 10% sensitivity and 100% specificity for diagnosing cellular leiomyomas. Leiomyomas with unusual growth patterns, such as parasitic leiomyoma, IV leiomyomatosis, disseminated peritoneal leiomyomatosis, and benign metastasizing leiomyoma, are histologic benign myomas that are thus not categorized as variants (Table 1). The World Health Organization has recently (2014) updated its criteria for mesenchymal tumors of the female reproductive tract [8], and variants of benign smooth muscle tumors are diagnosed according to their unusual histologic features.
