Abstract

The present study reports a case of histologically proven hepatic epithelioid angiomyolipoma that was evaluated with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd‑EOB‑DTPA)‑enhanced magnetic resonance imaging and diffusion‑weighted imaging. A 23‑year‑old female was admitted to the Northern Jiangsu People's Hospital (Yangzhou, Jiangsu, China) due to a 5.6‑cm mass in the liver, and a right partial hepatectomy was performed. Magnetic resonance imaging (MRI) revealed a hypointense mass on T1‑weighted imaging, and a hyperintense mass on T2‑weighted and diffusion‑weighted imaging, with a higher apparent diffusion coefficient value compared with normal liver parenchyma. On the dynamic Gd‑EOB‑DTPA‑enhanced MRI scan, the lesion manifested as hypervascular with multiple filiform vessels and a pseudocapsule image, and in the hepatobiliary phase the lesion demonstrated a lack of contrast retention, thus appearing hypointense compared with the background liver. Pre‑operatively, EMAL was diagnosed on the basis of these findings in the tumor. The optimum treatment is complete surgical excision and subsequent follow‑up. The patient was healthy and free from recurrence at 6 months and 1 year post‑surgery. Therefore, knowledge of EAML specific features on dynamic Gd‑EOB‑DTPA‑enhanced and DWI scans may improve the diagnostic accuracy of hypervascular hepatic tumors and may facilitate treatment selection.
