Hepatic angiomyolipoma (HAML) is a rare, benign tumor characterized by a mixture of fat, smooth muscle, and blood vessels. We present the case of a 37-year-old male with a history of tuberous sclerosis complex who underwent a CT scan to evaluate abdominal manifestations of the disease. The imaging was performed with and without contrast enhancement and analyzed across arterial, venous, and delayed phases. CT imaging revealed hepatomegaly with a large, ill-defined, nonencapsulated heterogeneous mass composed of both fatty and soft tissue components. Postcontrast enhancement demonstrated a heterogeneous pattern with arterial-phase vascular structures (branches of the hepatic artery) and venous-phase elements (branches of the portal vein network). The lesion extended to the superior, inferior, anterior, and posterior liver borders while preserving the biliary hilum. These imaging findings were consistent with hepatic angiomyolipoma; however, no biopsy was performed for histopathological confirmation. This study aims to highlight the CT characteristics of hepatic angiomyolipoma.
肝血管平滑肌脂肪瘤(HAML)是一种罕见的良性肿瘤,其特征是含有脂肪、平滑肌和血管成分。我们报告一例37岁男性病例,该患者患有结节性硬化症,接受了CT扫描以评估该病的腹部表现。扫描在有对比剂增强和无对比剂增强的情况下进行,并在动脉期、静脉期和延迟期进行分析。CT成像显示肝脏肿大,有一个大的、边界不清、无包膜的异质性肿块,由脂肪和软组织成分组成。对比剂增强后显示出异质性模式,动脉期可见血管结构(肝动脉分支),静脉期可见血管成分(门静脉网络分支)。病变延伸至肝脏的上、下、前、后边界,同时肝门部未受侵犯。这些影像学表现符合肝血管平滑肌脂肪瘤;然而,未进行活检以获得组织病理学确诊。本研究旨在强调肝血管平滑肌脂肪瘤的CT特征。
