Cystic central necrosis of transplanted pancreas.

The computed tomographic (CT) findings in pancreas transplant rejection have been reported to include graft swelling and inhomogeneity. We report a patient with transplant rejection in whom the preoperative CT examination and specimen radiographs revealed large cystic structures within the pancreas. Cystic central necrosis has previously been reported in patients with pancreatitis, but here it is associated with transplant rejection.
