Abstract
A spectrum of radiologic findings in cytomegalovirus (CMV) infection of the alimentary canal seen in 14 patients and correlated with pathologic examinations is described. Twelve patients had acquired immunodeficiency syndrome and two had no identified immunosuppression. Autopsies were performed on 12. Diffuse CMV colitis was present in eight patients, enteritis in seven, esophagitis in four, gastritis in two, cholangitis in one, and acute pancreatitis in one. Of 11 patients with enteritis and/or colitis seven had significant lower gastrointestinal bleeding and five died as a result of it. Radiologic findings in the gastrointestinal tract included superficial or deep mucosal ulcerations, perforation or fistula formation, luminal narrowing, rigidity and thickening of the intestinal wall, and inflammatory infiltration of the mesentery. These were seen on barium examinations and computed tomographic (CT) scans. Findings of pancreatitis were seen on CT scans in one patient. In another, a cholangiogram showed abnormal bile ducts caused by CMV cholangitis. The radiologist should be aware of the diverse manifestations of the disease and its likely occurrence in immunosuppressed individuals.
