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.
