The preoperative … Imaging of leiomyomas and their variants allows classification by location in the uterus and pretreatment planning. 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. After surgery, mass was found to be atypical leiomyoma. Degenerating Cystic Uterine Fibroid Mimics an Ovarian Cyst in a Pregnant Patient. The 43 years, patient presented with lump abdomen with heavy periods and anemia. However, frequently these tumors are not accompanied by symptoms, and they are found incidentally during computed tomographic (CT) examinations performed for other indications. In contrast to coagulative tumor cell necrosis seen in malignant leiomyosarcomas, infarction necrosis observed in ordinary benign leiomyomas is typically zonal, with necrotic smooth muscle cells surrounded by rims of granulation to hyalinized fibrous tissue. Unusual-appearing uterine masses may best be treated surgically with myomectomy or hysterectomy rather than medically or with interventional radiology (i.e., uterine fibroid embolization). The type of degenerative change depends on the degree and rapidity of the onset of the vascular insufficiency. 3B —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. When fibroids bec… Ultrasound and CT -Scan suggested “Ovarian Malignancy”!! Fibroids are uncommon before the onset of puberty and regress after menopause. CT is not the primary modality in the diagnosis of fibroid If the tumor is troubling you, or if it is growing rapidly, or the radiologist has other concerns, you should consider having it removed or you may be given other options such as embolization. This article reviews current approaches to the management of uterine fibroids, soft-tissue detail when compared with computed tomography (CT), and has a useful. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. 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. The typical appearance of leiomyoma is easily recognized on ultrasound but degenerations, as in our case may cause confusion in diagnosis. To our knowledge, there are no previous review articles in imaging journals addressing the many issues concerning leiomyoma variants. 3A —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. They occur in ~25% of women of reproductive age 1and are particularly common in the African population. However, the cystic areas do not enhance well and can be distinguished from other types of leiomyomas. Background/aims: The differential diagnosis of cystic uterine tumors includes fibroids showing cystic degeneration, cystic adenomyomas, congenital cysts, and developmental anomalies. If the address matches an existing account you will receive an email with instructions to reset your password. Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. This antiangiogenic mechanism is likely to be responsible for the cystic myoma degeneration in our case 4. Treatment. A subsequent CT scan (B) reveals an incidental calcified. An intermediate T2 signal and a high b value (1000 s/m2) signal were found in STUMPs and malignant tumors significantly more often than in benign tumors. Int J Gynecol Endsc 2017;1(1):46-49. C, Oblique sagittal IV contrast-enhanced scan shows that mass exhibits laminated pattern of enhancement consistent with myxoid leiomyoma. 8A —49-year-old woman with history of fibroids referred for MRI for before uterine fibroid embolization. The purpose of this article is to review the clinical, imaging, and pathologic features of leiomyoma variants. They were hypointense on T1-weighted scans (not shown). Some familial and sporadic syndromes with association of multiple cutaneous and uterine leiomyomas have been described [48]. They appear hypocellular with a myxoid matrix 6. After surgery, mass was found to be atypical leiomyoma. 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. 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]. Swelling of the abdomen. 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. 1, Seminars in Ultrasound, CT and MRI, Vol. Generally, the ultrasonic appearance of uterine fibroids is typical, and diagnosis is uncomplicated. The other was found to have a pelvic mass 20 months after a supracervical hysterectomy. 3C —48-year-old woman referred for MRI for further evaluation of possible ovarian mass on ultrasound and pelvic examination. One patient with STUMP was found to have implants on the rectosigmoid colon when undergoing surgical reexploration 102 days after a power morcellation procedure. Uterine fibroids can undergo hyaline, cystic, myxoid, and red degeneration. This is concerning for clinicians and radiologists alike, who both struggle with the same question: when should I refer a patient for MRI? 8, No. Computed tomography. Fig. Usually not: "cystic degeneration" usually means that a portion of the tumor has died as a result of its blood supply not always being adequate. Age and parity were significantly lower in patients with non-fibroid cysts. Fig. Introduction. By using the body’s natural pathways, the Interventional Radiologist will thread a tiny catheter through your arteries straight to the fibroid(s). Most uterine STUMPS are located in the corpus, but they can occur in the broad ligament, ovaries, cervix, or vaginal canal [37]. 9,22,23. 2B —53-year-old woman with indeterminate mass on ultrasound. Patient underwent … Ultrasound diagnosis was ovarian cyst. 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. B, Coronal T2-weighted scan shows that mass is intermediate signal intensity. However, because leiomyoma variants have lower recurrence rates and malignant potential, future guidelines for posttreatment surveillance might be less rigorous, weighing the possible benefits of CT surveillance against the risk of radiation exposure. Uterine fibroids are the most common of uterine benign tumors. Cystic Fibroids Degeneration Cystic degeneration is not so common type of fibroids degeneration; it affects only 4% of all fibroids and usually occurs after menopause. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm. 4B —45-year-old woman with symptomatic fibroids who underwent MRI for preoperative planning. Degenerating Cystic Uterine Fibroid Mimics an Ovarian Cyst in a Pregnant Patient. 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. Table 1 summarizes ordinary leiomyomas, including their various forms of degeneration, and their main variants. Being rare in prepubertal females, they commonly accelerate in growth during pregnancy and involute with menopause 1. Fig. 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. 4, International Journal of Paleopathology, Vol. 24: A. PDF | Uterine fibroids, also known as leiomyomas, are the commonest uterine neoplasms. 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. A, Axial T2-weighted scan shows well-defined moderate-signal intensity leiomyoma that actually was STUMP and several ordinary hypointense leiomyomas. Extremely prevalent, they occur in more than 20% of women older than 30 years (,1,,2). In contrast to ordinary leiomyomas, leiomyoma variants are neither well studied nor understood from an imaging perspective. Because leiomyomas may first be noted on CT scans, radiologists should become familiar with their characteristic appearance. However, leiomyomas vary widely in appearance and may be confused with other gynecologic malignancies. Cystic degeneration of fibroids should be considered as one of the differential diagnosis for all women presenting with acute abdominal pain. Leiomyoma with bizarre nuclei (also called atypical, sym-plastic, and pleomorphic) show the presence of scattered large atypical cells.
