A case of hepatic angiomyolipoma occurring in a 41-year-old woman, the eighteenth case in literature, is reported herein. The radiographic imagings of the tumor simulated those of focal nodular hyperplasia; namely, the tumor was hyperechoic on ultrasound, hypodense on computed tomography, hypervascular on angiography, and exhibited an uptake of technetium (Tc)-99m phytate. The diagnosis was established after successful removal of the huge tumor from the right hepatic lobe. Histologically, the tumor was angiomyolipoma which was made up of three components, blood vessels, smooth muscle and fatty tissue. Furthermore, extramedullary hematopoiesis, which is usually seen in this tumor was confirmed. The differentiation of hepatic angiomyolipoma from FNH is also discussed.
本文报道了一例发生在一名41岁女性身上的肝脏血管平滑肌脂肪瘤，这是文献中的第18例。该肿瘤的影像学表现类似于局灶性结节性增生；也就是说，肿瘤在超声检查中呈高回声，在计算机断层扫描中呈低密度，在血管造影中为高血管性，并摄取了锝（Tc）-99m植酸盐。在成功从右肝叶切除巨大肿瘤后确诊。组织学上，肿瘤为血管平滑肌脂肪瘤，由血管、平滑肌和脂肪组织三种成分组成。此外，还证实了通常在该肿瘤中可见的髓外造血。本文还讨论了肝脏血管平滑肌脂肪瘤与局灶性结节性增生的鉴别诊断。
