Computed Tomography of Retroperitoneal Castleman Disease (Plasma Cell Type) with Sonographic and Angiographic Correlation

Abstract

The CT and sonographic appearances of a case of retroperitoneal Castleman disease of the plasma cell type are reported along with angiographic correlation. In this case CT demonstrated a minimally calcified homogeneously enhancing retroperitoneal mass. Sonography showed the mass to be hypoechoic with good through transmission. The lesion was hypervascular with prominent early venous drainage on inferior mesenteric arteriography.
