Eosinophilic infiltration of duodenum and pancreatic head: report of a case studied arteriographically.

A case of tumorlike eosinophilic infiltration of the duodenum and pancreas is reported. Arteriography and hypotonic duodenography indicated a large lesion involving both the pancreatic head and the second portion of the duodenum without encasement or obstruction of the intrinsic vasculature. This is the first reported use of angiography in this condition. The combination of findings described should suggest a benign infiltrative process.
