Imaging characteristics of large lipoma and angiomyolipoma of the liver. Case reports

Abstract

A large lipoma and a large angiomyolipoma of the liver, one case each, are described. In the first case, a 24 × 14‐cm homogeneous mass demonstrated a fatty density (‐96H) on computed tomography (CT), echogenicity on sonography, and fine neovascular vessels on angiography in the right lobe of the liver. Histopathologic diagnosis of the resected specimen was lipoma. The second case showed a 9‐cm fatty mass (‐66H) with some enhanced interior nodules in the left lateral area of the liver on CT. Sonography disclosed a large echogenic mass with echolucent nodules, which were seen as stains on the angiogram. Angiomyolipoma was the histopathologic diagnosis. Among these diagnostic modalities, the CT scan provided the most specific and reliable findings. Both patients are doing well more than 2 years and 9 months after resection. Cancer 59:916‐921, 1987.
