Abstract

The imaging and pathological appearances of a hepatic angiomyolipoma are presented. On ultrasound (US), the mass was well-defined and echogenic. On computed tomography (CT), the lesion appeared of soft tissue density with peripheral foci of lower density. The case illustrates the difficulty of detecting the fatty content of a tumor by CT when the fatty content represents only a small portion of the lesion. Fine-needle aspiration (FNA) cytology and needle biopsy did not yield diagnostic material, and the tumor was resected.

摘要

本文展示了肝脏血管平滑肌脂肪瘤的影像学和病理学表现。超声检查（US）显示肿块边界清晰，呈高回声。计算机断层扫描（CT）显示病变为软组织密度，周边有低密度灶。该病例说明了当肿瘤的脂肪成分仅占病变的一小部分时，通过CT检测肿瘤脂肪成分的困难。细针穿刺抽吸（FNA）细胞学检查和针吸活检未获得诊断性材料，遂对肿瘤进行了切除。
