Uterine Lipoleiomyoma – A Rare Entity

Uterine lipoleiomyoma is a rare benign tumor with incidence of 0.03 to 0.2. We report a 46-year-old female patient with uterine lipoleiomyoma. She underwent total abdominal hysterectomy with bilateral salpingo-ooporectomy for menorrhagia. The histogenesis morphology and immunohistochemistry of this lesion are discussed.nbsp

Case report of a cervical lipoleiomyoma with an incidentally discovered ovarian granulosa cell tumor - imaging and minimal-invasive surgical procedure.

Uterine lipoleiomyomas are rare benign tumors that mostly affect the uterine corpus. We are reporting the imaging and operative procedure of a very rare case of a large lipoleiomyoma of the uterine cervix combined with an occult adult ovarian granulosa cell tumor. The patient was treated with minimal invasive surgery.

Lipoleiomyoma of uterus in a postmenopausal woman

Lipoleiomyomas are uncommon benign neoplasms of uterus and are considered to be a variant of uterine myomas. Their reported incidence varies from 0.03 to 0.2%. Lipoleiomyoma consists of variable proportion of mature lipocytes and smooth muscle cells. These tumors generally occur in asymptomatic obese perimenopausal or menopausal women. We report this case of uterine lipoleiomyoma because of its rarity.

Imaging Appearances of Uterine Lipoleiomyoma With Pathological Correlation—Report of Two Cases and Literature Review

In Brief Lipoleiomyomas are benign uterine neoplasms arising from the myometrium and composed of smooth muscle cells and mature adipocytes. We describe imaging and pathologic features of these rare neoplasms. In the first case, postcontrast computed tomography showed a well-demarcated mass with a large central core of fatty tissue. The tumor in the second case showed atypical magnetic resonance imaging findings. Fat content was minimal and followed the signal intensity of subcutaneous fat, appearing hyperintense on T1-and T2-weighted sequences. Fat-suppression sequences are useful in such cases for confirming the diagnosis. We have described the computed tomography and magnetic resonance imaging features of uterine lipoleiomyomas and the role of imaging in the diagnosis and surgical planning.

Uterine lipoleiomyoma: transvaginal ultrasound and computed tomography findings of an unusual entity

Uterine lipoleiomyoma is a rare benign tumor. It can be easily misdiagnosed as an ovarian origin teratoma on radiological imaging studies. We report a case of a patient with a uterine lipoleiomyoma as an incidental finding. Diagnosis of uterine lipoleiomyoma is possible with the use of ultrasound and computed tomography scanning of the abdomen and pelvis.

Uterine lipoleiomyoma in an elderly patient: a case report

Uterine lipoleiomyoma is a rare, fat-containing, benign tumor. The clinical features and optimal treatment of this tumor remain unclear. An 80-year-old woman with an extensive cardiac history was referred for assessment of a huge pelvic mass. Magnetic resonance imaging demonstrated a uterine tumor with inhomogeneously high signal intensity. A fat suppression technique showed heterogeneous suppression of the signal intensity, with areas of increased enhancement after Gd-DTPA administration. Hysteroscopy revealed no abnormal findings in the endometrium. She underwent a simple total abdominal hysterectomy, with a preoperative diagnosis of uterine liposarcoma. Histological examination revealed a uterine lipoleiomyoma. Ten days after surgery, she died due to acute non-occlusive mesenteric ischemia. In cases where the radiological appearance of a uterine tumor in an elderly patient is suspicious for liposarcoma, the possibility of a benign lipoleiomyoma should be considered. Careful consideration of the patient's preoperative condition and familiarity with uterine fat-containing tumors are essential for determining an optimal therapeutic approach.

MRI Findings of Uterine Lipoleiomyoma Correlated with Pathologic Findings

Our objective was to describe the MRI findings of uterine lipoleiomyoma and to correlate them with histopathologic findings. Uterine lipoleiomyoma typically presents as a well-demarcated mass showing hyperintensity with hypointense amorphous bundles on T1- and T2-weighted images with chemical shift artifacts. The hyperintense region suppressed on chemical shift fat-suppressed sequences and the hypointense bundles enhanced by contrast material pathologically correspond to mature fat tissue and smooth muscle tissue, respectively. Even in an atypical case with a small volume of fat tissue in the mass, a fat-suppression MRI sequence is especially useful for the diagnosis.

Significance of the “ beak sign”in the Differential Diagnosis of Uterine Lipoleiomyoma from Ovarian Dermoid Cyst

A case of uterine lipoleiomyoma in a 72-year-old woman is presented. Although a series of imaging studies suggested a lipomatous tumor, diagnosis was difficult because the tumor appeared as a pedunculated mass extending from the uterine body. To distinguish the tumor from an ovarian lipomatous tumor, the "beak sign" in a magnetic resonance imaging study was diagnostic in this case. The purpose of this paper is to review lipomatous masses of the female pelvis, to discuss the differential diagnosis of the unusual imaging features, and to discuss imaging techniques to optimize pelvic mass characterization.

Exophytic Lipoleiomyoma of the Uterus Mimicking Ovarian Teratoma: A Case Report

Lipoleiomyoma is a rare benign neoplasm of the uterus. I present here a case of exophytic uterine lipoleiomyoma in a 77-year-old woman. Due to its exophytic nature, this fatty tumor mimicked ovarian teratoma on the imaging studies.

Magnetic Resonance Imaging Features of Uterine Lipoleiomyoma

AbstractOur objective was to describe 3 previously unreported cases of uterine lipoleiomyoma as depicted on magnetic resonance imaging. We also reviewed the 9 prior magnetic resonance imaging cases of uterine lipoleiomyoma reported in the imaging literature in an attempt to define the imaging charac

Uterine lipoleiomyoma containing metastatic breast carcinoma: a case with two unusual pathologies

Uterine lipoleiomyoma is a rare benign tumor. Besides this, metastasis to this tumor from breast carcinoma is extremely rare without any case reported in the literature. We report one such case of metastatic carcinoma in uterine lipoleiomyoma from primary breast cancer.

Lipoleiomyom - eine seltene Uteruspathologie

Wir berichten über eine 62-jährige Patientin mit der seltenen Diagnose eines Lipoleiomyoms des Uterus. Die Läsion wurde als Zufallsbefund entdeckt und konnte präoperativ nicht diagnostiziert werden. Es wird ausführlich über die bildgebenden Verfahren sowie die histologischen Gegebenheiten dieser sehr seltenen Tumorentität berichtet. Sowohl die möglichen Entstehungsmechanismen als auch die klinisch pathologischen Besonderheiten werden besprochen.

Uterine lipoleiomyomas: US and CT findings

Fatty tumors of the uterus are rare. The reported incidence differs, from 0.03% to 0.2%. Two new cases of uterine lipoleiomyoma are presented with ultrasound, computed tomography, and pathologic correlation. To date, only seven cases have been reported in the radiologic literature.

Dysregulation ofHMGIC in a uterine lipoleiomyoma with a complex rearrangement including chromosomes 7, 12, and 14

Uterine lipoleiomyomas are extremely rare tumors consisting of a mixture of mature adipocytes and smooth muscle cells. Using G-banding and FISH, we characterized a complex rearrangement involving chromosomes 7, 8, 10, 11, 12, and 14 in one of these tumors. The region 14q23-24 was inserted into the long arm of the derivative chromosome 12, between the 3' end of HMGIC and 7q21-22, another region often rearranged in uterine leiomyomas. Other portions of chromosomes 12 and 14 were involved in derivative chromosomes 7, 11, 12, and 14. A chromosome 8 was involved in a three-way rearrangement including the derivative 7, a ring chromosome 10, and a small derivative chromosome 8 bearing segments of chromosomes 10 and 11. No abnormality of chromosome 5 was detected, in contrast to two previously reported cytogenetic analyses of uterine lipoleiomyoma. The consistent finding of chromosomes 12 and 14 on different derivatives indicates that the t(12;14) was a primary event. In addition, immunohistochemical studies showed that HMGI-C was aberrantly expressed in this tumor. These observations suggest that uterine lipoleiomyomas have a pathogenetic origin similar to that of typical leiomyomas. Genes Chromosomes Cancer 27:209-215, 2000.
