Retroperitoneal Castleman's Disease of the Hyaline Vascular Type Presenting Arborizing Calcificatio

Abstract

Castleman's disease (CD) usually manifests as a solitary mediastinal tumor and only rarely as an isolated retroperitoneal mass. In the latter instances it is difficult to distinguish radiographically from other retroperitoneal masses. We report a 22-year-old female patient with retroperitoneal CD of the hyaline vascular type presenting with arborizing calcification. This characteristic calcification pattern is considered unique to CD, and is useful in diagnosis when present.
