摘要
目的探讨2例经病理证实的肝脏上皮样血管平滑肌脂肪瘤(epithelioid angiomyolipoma,EAML)的CT表现。方法回顾分析2例经手术病理证实的肝脏EAML CT资料并结合文献讨论。结果 2例均为女性,年龄分别为38岁和49岁,1例上腹部疼痛,另1例因右侧下腹部包块就诊时偶然发现。实验室检查均未见异常。CT表现:肿瘤分别位于肝Ⅱ/Ⅶ段;平扫均呈稍低密度,其中例1内见少量脂肪成分;动态增强扫描分别呈"快进慢出"、"快进快出"强化方式,动脉期均可见增粗、迂曲的供血血管影;病例1动态增强示大片边界清楚的囊性密度区。结论肝脏EAML CT像上具有一定的特征性,表现为富血供、含少量或不含脂肪成分,内部可见边界清楚的囊性密度区。病灶缺乏脂肪成分、强化方式呈"快进快出"时易误诊为肝细胞癌。
Objective To analyze the CT features of EAML in liver. Methods CT features of two patients with EAMLwere reviewed. Results Both of the 2 patients were females, age of 38 and 49 years old respectively. One case presented with right upper abdominal pain, and another one was occasionally detected the low right abdominal mass. The la- boratory examinations were normal in both cases. CT findings：（ 1 ）The masses located at segment Ⅱ/Ⅶ respectively; （2） Both lesions presented as hypoatteunuation on non-enhanced CT, little fat components was detected in 1 case ; （ 3 ） On con- trast-enhanced CT, both lesions manifested as hypervascular lesion with obvious enhancement and curved thicking supplying artery on arterial phase. Conclusion Epithelioid angiomyolipoma of liver has characteristic CT findings, including hyper- vascular lesion with little or no fatty components, and the cystic areas can be detected in some cases. It is prone to be mis- diagnosed as liver cancer.
