The authors present six cases of Castleman's disease. One was located in the left middle lung near the lung root, one in the right posterior mediastinum, one in the gallbladder fossa, one in the left perinephric space, and the last two in the mesenteric region. All the hyaline-vascular type showed good enhancement after contrast medium injection. The only one case of plasma cell type located in mesentery was not enhanced after contrast injection. Ultrasound of abdomen was performed in one of the six patients, which showed homogeneous and hypoechoic in echo-pattern.
