Hibernoma-case report and literature review.
Hibernoma is an uncommon benign fatty tumor that arises from the vestiges of fetal brown fat. We present a case report of a hibernoma of the back in a symptomatic 42-year-old man and describe the important clinical, histopathologic, and imaging findings. Computed tomography shows a well-defined hypodense mass with septations. Magnetic resonance imaging shows intermediate T1 and bright T2 signal of the mass and also demonstrates the characteristic marked contrast enhancement.DOI: 10.1097/DAD.0b013e3181a51bd8
