摘　　要：目的探讨肝脏上皮样血管平滑肌脂肪瘤(HEAML)的影像学特点及误诊分析。方法回顾性分析4例经手术病理证实的HEAML的临床及影像特点。结果4例均为单发病灶;1例含微量脂肪,3例不含脂肪;2例为类圆形,2例为浅分叶;3例有假包膜,1例无假包膜且密度/信号不均;增强扫描后1例快进快出,3例快进慢出;3例周边见动脉血管,病灶内部有少许血管样结构,静脉期及延迟期仍强化,1例未见明显中央/周边血管。结论HEAML的影像学表现具有一定的特征,但缺乏特异性,鉴别诊断仍较为困难,需结合临床资料综合分析。Abjective To investigate the imaging characteristics and misdiagnosis of Hepatic Epithelioid Angiomyolipoma(HEAML).Methods The clinical and imaging features of 4 cases of HEAML confirmed by surgery and pathology were retrospectively analyzed.Results All 4 cases were single lesions.One case contained trace fat,and 3 cases contained no fat.2 cases were orbicular,and two were superficial lobed.3 cases had false capsules,1 case had no false capsules,and the density/signal was uneven.After enhanced scanning,1 case was fast in and fast out,3 cases were fast in and slow out.Peripheral arterial vessels were observed in 3 cases,and there were a few vascular structures in the lesion,which were still strengthened in the venous stage and delayed stage,and no obvious central/peripheral vessels were observed in 1 case.Conclusion The imaging findings of HEAML have specific characteristics but lack specificity,and the differential diagnosis is still difficult,requiring comprehensive analysis with clinical data.
