CT findings of castleman disease (giant mediastinal lymph node hyperplasia)

ABSTRACT

Castleman disease is a rare disease entity of unknown etiology, with the characteristics of large, wellmarginated benign lymphoid masses occuring predominently in the mediastinum. the value of contrast enhancement insolid soft tissue masses of mediastinum has little been written because most of the solid mediastinal tumors showno significant degree of enhancement. But Castleman disease, because of its hypervascularity, shows significantdegree of enhancement in most cases. Authors report 3 cases of Castlemen disease and suggests good diagnosticprobability of Castlman disease in cases that show benign looking homogeneously enhancing mediastinal mass by CTscan.
