A Case of Colonic Stricture Caused by Cytomegalovirus Colitis in a Patient with Acute Respiratory Distress Syndrome

Cytomegalovirus (CMV) infection has been described in immunosuppressed individuals such as patients with AIDS, those receiving chemotherapy, and post-transplantation. CMV can cause severe disease either via reactivation of latent virus or via primary infection. In immunocompetent patients, CMV infection is usually transient and does not exhibit many symptoms. The colon is the site most frequently affected by severe CMV disease in immunocompetent patients. Clinically, CMV colitis commonly presents with diarrhea, fever, and abdominal pain. Although some patients recover spontaneously, others suffer from severe complications, such as bowel perforation, severe gastrointestinal bleeding and, rarely, stricture, and surgery is the choice of treatment in these patients. We report a case of stricture of the proximal transverse colon, presenting as a complication of CMV colitis, in an immunocompetent man with acute respiratory distress syndrome. We performed laparoscopic segmental resection of the proximal transverse colon. (Korean J Med 2013;84:284-289)
