Extensive mesenteric inflammatory veno-occlusive disease of unknown etiology after primary cytomegalovirus infection: first case.

Abstract

We report a young man who, shortly after a primary cytomegalovirus infection, presented with signs of intestinal ischemia requiring surgical intervention. The resected specimen of small bowel showed striking features of extensive phlebitis and venulitis affecting virtually all of the veins of the small intestine and mesentery. Although he had had a recent primary cytomegalovirus viremia, we could not identify any evidence of cytomegalovirus in the small bowel. He was not infected with HIV. The entity we describe is different from the recently reported mesenteric inflammatory veno-occlusive disease. The clinicopathologic entity represented by our patient's disease was heretofore unrecognized.
