A 30-year-old woman was hospitalized in our institute with fever up and abdominal pain. Computerized tomography showed a retroperitoneal mass (8 cm in diameter) with arborizing calcification, which was enhanced homogeneously in the arterial phase. The operation was performed and parthological diagnosis revealed hyaline vascular type Castleman's disease. This characteristic calcification pattern is considered unique to Castleman's disease, and could be useful for future diagnosis.
