CT features of castleman disease of the abdomen and pelvis

Abstract

OBJECTIVE. The purpose of this study was to describe the CT features of Castleman disease in the abdomen and pelvis. CONCLUSION. The most frequent appearance of abdominal or pelvic Castleman disease is of a single, well- defined enhancing mass. Smaller tumors (<5 cm) display homogeneous contrast enhancement; larger tumors (>5 cm) show heterogeneous enhancement and attenuation when correlated with central necrosis and degeneration. Calcification was seen in 31% of the cases. Castleman disease may be considered in the differential diagnosis of a discrete enhancing mass in the abdomen or pelvis.
