Methods Retrospective analyzed of 9 cases with complete clinical and pathological data of the CT findings of Castle man disease. Results CT scans of 9 cases showed a solitary soft tissue mass, diameter 4-9 cm. Unenhanced CT value 28- 46 HU, enhanced scan in early remarkably homogeneous enhancement, high CT value for 110-187 HU, venous phase CT values for 106-128 HU, CT values for 98-110 HU delay period between. Pathology includes hyaline vascular type in 8 cases and 1 case of mixed type. In 3 cases accompanied with central branching or punctate calcification. Conclusion The limitations of Castleman disease manifested as solitary soft tissue masses, enhanced or central with branching calcifi cation of the special signs, CT scanning for the diagnosis of disease that has important significance.
