Abstract

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.

摘要

冬眠瘤是一种罕见的良性脂肪肿瘤，由胎儿棕色脂肪遗迹产生。我们报告一例42岁有症状男性背部冬眠瘤的病例，并描述重要的临床、组织病理学和影像学表现。计算机断层扫描显示一个边界清晰、有分隔的低密度肿块。磁共振成像显示肿块在T1加权像呈中等信号，T2加权像呈高信号，且有特征性的明显强化。
