Abstract

A case of hepatic angiomyolipoma and its imaging features are presented. Computed tomography of the liver showed a low-density mass without obvious fat. T1-weighted magnetic resonance images revealed a low-signal-intensity mass containing some tiny high-signal-intensity foci. One of the high-signal-intensity foci was found by histology to represent the fat component of the tumor.

摘要

本文报告一例肝血管平滑肌脂肪瘤及其影像学特征。肝脏计算机断层扫描显示一个低密度肿块，无明显脂肪成分。T1加权磁共振图像显示一个低信号强度肿块，内有一些微小的高信号强度灶。组织学检查发现其中一个高信号强度灶代表肿瘤的脂肪成分。
