A 63-year-old woman was admitted to this institution for further examination of a liver tumor. Ultrasonography revealed a hypoechoic mass of 1.7 cm in diameter in S4 of the liver. The tumor was strongly enhanced during the arterial phase of enhanced CT, and appeared washed out during the portal venous phase. T1-weighted MRI showed a slightly low intensity mass, and T2-weighted MRI showed a high intensity mass. Splanchnic angiography revealed a prominent hypervascular mass in arterial phase. Although the tumor contained very little fat tissue, HMB-45 stain was useful in pathological diagnosis of this case of hepatic angiomyolipoma.
