A case of chest wall Castleman's disease.

We describe the findings of a rare case of right anterior chest wall Castleman' s disease of the hyaline vascular type. It manifested as a solitary mass, 7.5 x 4.5 x 3.0 cm in size, with incomplete border and extrapleural signs on chest roentgenograms. The mass was hypoechoic with numerous tiny bright spots on US; it enhanced homogeneously on CT, had a homogeneously high intensity on both T1- and T2-weighted MR images, and showed rich vascularity with homogeneous capillary blush on internal thoracic arteriogram.
