Insights into hepatic angiomyolipoma: A case report highlighting scannographic findings

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.
