A case of Castleman's lymphoma at the hepatic hilum is reported. A 60-year-old woman was admitted to our hospital with the complaint of epigastralgia. Abdominal ultrasonography revealed a well-defined mass below the liver. Abdominal computed tomography revealed a mass with calcification, magnetic resonance imaging (T₂ weighted) showed a mass whose signal was higher than that of the liver, and abdominal angiography showed a hypervascular mass. Laparotomy was performed. A walnut-sized tumor was noted at the liver hilus and the tumor was resected. The resected tumor, measuring 4.0×3.5×2.8 cm, was completely enclosed within a thin capsel. Histological examination revealed characteristics of the hyaline-vascular type of Castleman's lymphoma.
