Hibernoma of the thigh: a report of four cases.

چکیده
Hibernoma is a rare benign adypocyte tumour of brown fat. We report on 4 patients with hibernoma of the thigh. Clinical features and magnetic resonance imaging suggested the tumours were liposarcomas, but biopsy yielded the diagnosis of hibernoma. All 4 patients underwent complete excision of the tumour and had no recurrence.

Hibernomas are extremely rare benign tumors of adipose tissue characterized by an admixture of brown fat cells with granular, multivacuolated cytoplasm and white fat cells. Hibernomas account for 1.6% of benign adipose tissue tumors and approximately 1.1% of all adipocytic tumors. Around 10% of these cases are intramuscular.

متن کاملHibernoma in the Thigh Mimicking Soft Tissue Sarcoma on FDG-PET
Hibernoma, a tumor of benign brown adipose tissue can present as a large mass that can mimic a sarcoma. Imaging characterization of large extremity tumors can be very helpful in assessment of these masses for treatment planning and follow-up. We report on a case where FDG-PET imaging was performed on a patient with a large thigh mss, suspected to be a sarcoma. The FDG-PET uptake was highly avid...
