A man in his thirties was admitted to the Infectious Disease Center of this institution complaining of severe watery diarrhea which had continued for 3 months or more. Results of blood tests were positive for both HIV antibody and cytomegalovirus (CMV) antigenemia. Ultrasonography showed diffuse wall thickening of the entire colon, and stratification of the wall was indistinct. Colonoscopy revealed shallow ulcers, and cytomegalovirus colitis was diagnosed from the biopsy specimen from the ulcerated region. Although ultrasonographic images of inflammatory bowel disease and infectious colitis are frequently reported, this might be the first report of an ultrasonographic image of cytomegalovirus colitis.
