10 patients with pathologically proved Castleman disease in the abdomen and pelvis were examed with CT & MRI.The lesions were divided into those with localized (n=9) and disseminated (n=1). The pathologic subtypes of all 9 cases of localized disease were hyaline vascular type.The most suggestive CT & MRI features of localized & hyaline vascular type of Castleman disease include a single larger mass or a single dominant mass with small satellite nodules, enhanced sharply with the attenuation similar to large arteries and areas of central lower radial attenuation with in the larger tumor after intravenous injection of contrast media.The pathologic subtypes of 1 cases of disseminated disease were plasma cell type which manifested as several well-defined nodules lied in the retroperitoneal zone that enhanced sharply with the attenuation similar to large arteries after intravenous injection of contrast media.
