Abstract

|
Cytomegalovirus (CMV) colitis is a common opportunistic infection in immunocompromised patients. Affected individuals present with abdominal pain, diarrhea, or hematochezia. Complications of CMV colitis can include massive bleeding, toxic megacolon, bowel perforation and, rarely, colon stricture. A 69-year-old woman who had no specific past history was admitted to the orthopedic department for pelvic bone fracture with right iliac artery rupture caused by a traffic accident. She was successfully managed with emergency transarterial coil embolization. After 2 weeks, she developed hematochezia and recurrent abdominal pain. Colonoscopy showed a huge, deep ulcer in the rectosigmoid colon. Biopsy and immunohistochemical staining revealed giant cells with intracellular inclusion bodies that were positive for CMV antigen. She received antiviral treatment after which her symptoms improved. On follow-up colonoscopy 3 months later, we found a tight luminal narrowing in the rectum. We did a repeat endoscopic balloon dilation in this patient and she experienced improvement.
