cystic degeneration of fibroid ct

In summary, at the present time, there are no official guidelines for clinical follow-up for leiomyoma variants. [10] reported an isolated case of a mitotically active leiomyoma in a 68-year-old woman treated with a hysterectomy that recurred 7 months later as a leiomyosarcoma, the authors noted no prior published reports of this phenomenon among the 89 previously reported cases of mitotically active uterine leiomyoma. 13, Journal of Evolution of Medical and Dental Sciences, Vol. The 43 years, patient presented with lump abdomen with heavy periods and anemia. No matter how severe the pain is, it is not life threatening. 1). B, Coronal T2-weighted scan shows that mass is intermediate signal intensity. The typical appearance of leiomyoma is easily recognized on ultrasound but degenerations, as in our case may cause confusion in diagnosis. [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%). B, Oblique axial T2-weighted scan shows that mass arises from uterus and has peripheral high signal intensity with laminated low signal intensity. Fig. 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. 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. However, the sonographic characteristics of fibroids undergoing cystic degeneration, and especially those of the submucous type, may be misleading. The ultrasonographic and contrast-enhanced computed tomographic findings of this case were characteristic of ovarian neoplasm. 24, No. Large or small cystic spaces develop in the edematous, acellular center (, 1,, 5,, 6). 5A —39-year-old woman with pelvic pain and presumed ordinary leiomyoma after receiving therapy with leuprolide acetate (Lupron, Abbvie). A, Axial T1-weighted scan shows homogeneously low-signal intensity adnexal mass. Being rare in prepubertal females, they commonly accelerate in growth during pregnancy and involute with menopause 1. Fig. Patients with STUMP may require closer surveillance than a yearly examination and may need a consultation with a gynecologic oncologist.” On the basis of the available literature, the authors recommended no additional surveillance of patients who undergo a hysterectomy and are found to have an atypical leiomyoma. A, Axial T1-weighted image shows isolated large subserosal isointense well-circumscribed mass. A, Axial T2-weighted image shows several well-circumscribed hypointense submucosal intramural and subserosal leiomyomas. 31, No. 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. CT. fibroids are usually seen as soft tissue density lesions and may exhibit coarse. Ordinary leiomyomas can degenerate in many ways (Table 2). MRI showed large multiseptated cystic mass 21 × 16 cm × 12 cm in the right. Hyaline cystic degenerations of the uterine fibroids may be rare but not uncommon. Fig. Cystic degeneration may be considered an extreme sequela of edema and is observed in about 4% of leiomyomas (, 1). C, Axial T1 fat-suppressed IV contrast-enhanced scan shows homogeneous enhancement. Introduction. 18, American Journal of Roentgenology, Vol. There is now a published series of six patients with STUMPs treated with power morcellation techniques [16]. 2, No. No matter how severe the pain is, it is not life threatening.

On T1-weighted images, there was high signal intensity indicative of hemorrhagic necrosis in the sarcomas, not seen in the other lesions (Fig. 2, No. D, Representative histologic specimen of uterine STUMP shows marked cellularity and cytologic atypia (but mitotic count < 10/10 high-power fields). Imaging Features of Postoperative Complications After Spinal Surgery and Instrumentation, Review. A CT scan of the abdomen and pelvis performed to exclude a surgical cause showed a 7.3×10.0×12.0 cm mass arising from the posterior wall of the uterus with irregular margin inferiorly representing a fibroid with degeneration, infarction or, less likely, malignant changes and surrounding mesenteric inflammation . 205, No. For example, in a recent article in which whole-genome sequencing and gene-expression profiling were performed on 38 uterine leiomyomas [5], identical genetic variants were seen in separate tumors, suggesting a common origin; these authors conclude that, “an accurate molecular classification of uterine leiomyomas …. In addition, studies have shown that cellular leiomyomas can significantly decrease in size after gonadotropin-releasing hormone therapy compared with degenerated leiomyomas [36]. 20: Red (hemorrhagic) degeneration of UF is characterised by variable signal. Atypical leiomyomas (Fig. Uterine leiomyomas and leiomyosarcomas are at opposite ends of the pathologic spectrum of uterine smooth muscle tumors. This antiangiogenic mechanism is likely to be responsible for the cystic myoma degeneration in our case 4. However, frequently these tumors are not accompanied by symptoms, and they are found incidentally during computed tomographic (CT) examinations performed for other indications. Radiologist suggested that leiomyoma could be smooth muscle tumor of uncertain malignant potential, so patient underwent myomectomy. C, Axial T1-weighted fat-suppressed scan shows associated loss of signal intensity in anterior aspect of mass, compatible with fat. For this reason, the role of immunohistochemical studies including p53 and p16 has been established [51–58]. Nov 1, 1990. The typical appearance of a … The 43 years, patient presented with lump abdomen with heavy periods and anemia. CT Diagnosis of Acute Mesenteric Ischemia from Various Causes, Pictorial Essay. 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. smooth muscle tumors of uncertain malignant potential, MR Imaging Differentiation of Soft-Tissue Hemangiomas from Malignant Soft-Tissue Masses, Review. Corresponding Author. Uterine fibroids can undergo hyaline, cystic, myxoid, and red degeneration. Differential diagnosis of a malignancy should be considered in women presenting with a uterine mass, particularly if they are postmenopausal.6 One to two in 1000 women with uterine masses are estimated to have a uterine malignancy.7 Suspicion for malignancy is raised for rapidly growing fibroids, particularly in postmenopausal women who are not on hormone replacement therapy, and women responding poorly to gonadotrophin releasing hormone (GnRH) agonists. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm mimicking malignant ovarian tumor. However, overwhelmingly, the leiomyoma variants behave in a clinically benign fashion and require no adjuvant therapy [8]. As fibroids enlarge, they outgrow their blood supply which may evoke cascade of inflammatory reactions and ischaemic changes leading to various types of degenerations. Fig. 2B —53-year-old woman with indeterminate mass on ultrasound. The purpose of this review is thus to summarize the relevant clinical, imaging, and pathologic findings of leiomyoma variants. However, other investigators, such as Ip et al. For patients with STUMP lesions regardless of the surgery performed, the authors recommend baseline CT of the chest, abdomen, and pelvis and then routine physical examinations, including pelvic examinations, every 6 months for 5 years and then annually thereafter because recurrences often present as pelvic or abdominal masses or as pulmonary metastases [18, 19]. Patients with mitotically active leiomyomas and cellular leiomyomas are usually cured with surgery, and no additional postoperative surveillance is routinely necessary. Taran et al. Fig. 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. 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. [9] reviewed 127 patients representing the pathologic spectrum, from uterine leiomyomas to leiomyosarcomas, using World Health Organization and Stanford criteria. The patient underwent a laparotomy. In addition, infarction, hemorrhage, hyalinization, and hydropic changes are also commonly present. This article reviews current approaches to the management of uterine fibroids, soft-tissue detail when compared with computed tomography (CT), and has a useful. In other instances the women we see have numerous–up to 20–small. the degeneration – hyaline, cystic, myxoid, red degeneration and dystrophic. If disease is present, then more-intense imaging surveillance could be considered, but guidelines have not yet been established. 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]. Cellular leiomyomas are more likely to be singular and larger than ordinary leiomyomas; there is also a higher likelihood that endometriosis or adenomyosis is absent, that the patient is symptomatic with menometrorrhagia, and that the indication for the imaging study is “enlarging leiomyoma” [11]. Subserous fibroids—these fibroids grow predominantly outside the uterus and bulge. View 9,22,23. Cystic degeneration of fibroids should be considered as one of the differential diagnosis for all women presenting with acute abdominal pain. Your doctor may feel moderate and large uterine fibroids during a routine. Uterine STUMPs have been only sporadically described in the imaging literature given their rareness. 1, Seminars in Roentgenology, Vol. Many myomectomies are performed in women who wish to preserve fertility or do not want to undergo a hysterectomy; in such cases, it would seem prudent to avoid morcellation procedures to remove an unusual-appearing fibroid if preoperative imaging studies raise the possibility of a leiomyoma variant. Typical appearance of fibroid uterus on CT. They occur in ~25% of women of reproductive age 1and are particularly common in the African population. Ultrasonography and CT revealed a large solid mass with cystic areas extending into both uterine adnexa. non-degenerated fibroids and calcification appear as low to intermediate. These authors suggested reexploration of patients with STUMP who had undergone morcellation techniques to stage and resect STUMP lesions that might have been disseminated as a result of surgical morcellation. Fig. Leiomyomas with unusual growth patterns (e.g., dissecting leiomyoma, diffuse and IV leiomyomatosis, and benign metastasizing leiomyoma) have the benign cytologic features of ordinary leiomyomas [47]. 3, Journal of Minimally Invasive Gynecology, Vol. Fig. 3) because of the intense enhancement of the stroma with no enhancement of the intervening mucinous lakes [34]. 29, No. Myxoid degeneration of a leiomyoma is one of the rarer types of degeneration that can occur in a standard uterine leiomyoma. Transabdominal biopsy confirmed benign, degenerating fibroid. 189, No. It is rare for this condition to manifest as acute symptoms necessitating emergency surgical intervention. 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. Jun 26, 2016. Fever in addition to other symptoms. 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]. PDF | Uterine fibroids, also known as leiomyomas, are the commonest uterine neoplasms. B, Sagittal T2-weighted fat-suppressed scan shows amorphous moderate-signal-intensity tissue that has poorly defined margins with myometrium. The presence of a T2-hyperintense rim indicates a pseudocapsule of edema secondary to some degree of venous or lymphatic obstruction [29]. Fig. Journal of Evolution of Medical and Dental Sciences, Vol. The two leiomyoma variants that require clinical and imaging surveillance after myomectomy are atypical leiomyoma and STUMP. There was no sign of appendicitis. Fig. One patient with STUMP was found to have implants on the rectosigmoid colon when undergoing surgical reexploration 102 days after a power morcellation procedure. There are no standard criteria for monitoring patients with atypical leiomyomata or STUMP tumors. 11, Canadian Association of Radiologists Journal, Vol. Uterine fibroid vascular supply from … Cystic degeneration occurs in 4% of cases and is considered an extreme sequel of edema. Table 1 summarizes ordinary leiomyomas, including their various forms of degeneration, and their main variants. Degenerating Cystic Uterine Fibroid Mimics an Ovarian Cyst in a Pregnant Patient. 4A —45-year-old woman with symptomatic fibroids who underwent MRI for preoperative planning. Case reports [43, 44] have also reported these findings on conventional sequences. Linear signal void along posterior fundus represents prior myomectomy changes after removal of conventional fibroid. Leiomyosarcomas, on gross pathologic analysis, typically are large solitary masses with a diameter greater than 10 cm and are not well circumscribed (i.e., with infiltrating margins) [8]. The cystic spaces have markedly increased SI on T2-weighted images and do not enhance on contrast-enhanced imaging . 5B —39-year-old woman with pelvic pain and presumed ordinary leiomyoma after receiving therapy with leuprolide acetate (Lupron, Abbvie). 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. Precise knowledge of the histopathologic backgrounds of degeneration and the clinical course helps u… Decreased blood supply to the fibroids may influence liquefaction of hyalinized areas that are seen as cystic changes on the … There are no clinical findings that reliably differentiate ordinary leiomyomas from leiomyoma variants and leiomyosarcomas. Although CT is not a recommended imaging modality for the evaluation of leiomyomas, they are frequently incidentally seen, usually appearing as a variably enhancing mass, sometimes with dystrophic calcifications [24]. 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. Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. Because of moderate signal intensity on T2-weighted scans, mass was thought to be smooth muscle tumor of uncertain malignant potential, but at pathologic analysis, it was determined to be cellular myoma. 6A —45-year-old woman who underwent MRI to evaluate size of uterine fibroids. C, Oblique sagittal IV contrast-enhanced scan shows that mass exhibits laminated pattern of enhancement consistent with myxoid leiomyoma. 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. Rates of symptomatic women (60 vs. 55.6%) were similar in both groups. As fibroids enlarge, they may outgrow blood supply and they may degenerate. Results were read as fibroids, but at pathologic examination, large mass was found to be smooth muscle tumors of uncertain malignant potential (STUMP). 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. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm mimicking malignant ovarian tumor. 8, No. 19, 2 December 2016 | Indian Journal of Gynecologic Oncology, Vol. B, Axial T1-weighted fat-suppressed unenhanced scan is unremarkable. Uterine leiomyomas, commonly known as fibroids, are one of the most common pelvic tumors found in women. Large fibroids often undergo hyaline, cystic, and at times, red degeneration. study (CT or magnetic resonance imaging (MRI)) is mandatory to evaluate. A case of massive cystic degeneration in a uterine fibroid 21 cm × 16 cm × 12 cm. 2A —53-year-old woman with indeterminate mass on ultrasound. Fig. This is concerning for clinicians and radiologists alike, who both struggle with the same question: when should I refer a patient for MRI? B, Axial nonfat-suppressed T1-weighted image shows T1 hyperintensity anteriorly within mass, compatible with fat. If the address matches an existing account you will receive an email with instructions to reset your password. Affiliations. Some familial and sporadic syndromes with association of multiple cutaneous and uterine leiomyomas have been described [48]. 8B —49-year-old woman with history of fibroids referred for MRI for before uterine fibroid embolization. Fig. Fig. 4, Korean Journal of Radiology, Vol. For example, in one of the largest series on this variant, Ly et al. 2). An icon used to represent a menu that can be toggled by interacting with this icon. Maria Luisa C. Fogata MD. After surgery, mass was found to be atypical leiomyoma. The National Comprehensive Cancer Network Clinical Practice Guidelines for posttreatment surveillance of leiomyosarcomas include physical examination every 3–4 months for 2 years as well as imaging of the chest, abdomen, and pelvis every 3–4 months for 2–3 years, then every 6–12 months for the next 2 years. On ultrasound, the detection of hypervascularity in a large solitary uterine mass can identify suspicious masses, such as a leiomyosarcoma [27]. 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). 6B —45-year-old woman who underwent MRI to evaluate size of uterine fibroids. 22, No. Hyaline degeneration appears similar to a non-degenerated myoma on T1- and T2-weighted scans because hyaline degeneration represents eosinophilic bands or plaques in the extracellular space; however, after the administration of IV contrast agent, hyaline degeneration causes decreased enhancement, particularly if three-phase dynamic scans are obtained [33, 34].
