Multimodal Imaging of Hepatic Angiomyolipoma: CT and MRI Findings in a Sporadic Case.

Abstract

Astract: Hepatic angiomyolipoma (HAML) is a rare benign mesenchymal tumor composed of variable proportions of adipose tissue, smooth muscle, and blood vessels. While renal angiomyolipomas are relatively common, their hepatic counterparts are exceedingly rare and often pose a diagnostic challenge. Differentiating HAML from malignant lesions, particularly hepatocellular carcinoma (HCC) containing fat, is crucial for patient management. A female patient presented for routine abdominal evaluation. The acquired Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) revealed a well-circumscribed hepatic lesion with demonstrable macroscopic fat. The diagnosis was confirmed by analyzing the imaging characteristics.
