Abstract
A 65-year-old woman was admitted to the other hospital because of diarrhea and abdominal pain. Colonoscopy showed ulcers spreading widely and annularly in the descending colon. There was no improvement under conservative therapy. Therefore she was given steroid under the diagnosis of Crohn's disease. Since her symptoms got worse when she started to inject meal orally, she was transferred to our hospital. Because biopsy specimen from the ulcer in the descending colon showed inclusion bodies in the cell nuclei, we administered ganciclovir to her under the diagnosis of CMV infection. Although laboratory data improved, X-ray showed bowel stenosis, hence left hemi-colectomy was performed.
