Epithelioid Angiomyolipoma of the Liver

Excerpt

A 40-year-old female sought medical help because of recurrent episodes of urinary tract infection. A liver mass was found incidentally during renal ultrasonographic examination. Laboratory tests showed normal liver function and negative hepatitis B or C markers. Tumor markers such as alpha-fetoprotein (2.32 ng/mL; normal, < 7), carcinoembryonic antigen (0.7 ng/mL; normal, < 3.8), and carbohydrate antigen 19–9 (9.63 U/mL; normal, < 27) were not elevated. Abdominal computed tomography (CT) with contrast revealed a 5-cm mass with enhancement in the arterial phase (Fig. 1a) and rapid washout in the portal venous phase (Fig. 1b) over segments 5 and 6 of the liver. Interspersed fatty component was noted in the lesion. Early appearance of the draining right hepatic vein was also noted on both CT (Fig. 1c) and hepatic angiogram (Fig. 1d).
