Abstract
A 70-year-old male visited our hospital complaining of diarrhea and hematochezia.
Abdominal CT demonstrated multiple sigmoid colonic diverticula and inflammatory changes suggestive of diverticulitis. Colonoscopy revealed diverticula scattered in the sigmoid colon with localized mucosal edema and erosion. A colonoscope could not be passed through the sigmoid colon due to the presence of a stricture. Histological analysis of biopsy specimens showed areas of inflammatory cell infiltration, crypt abscesses and granuloma formation in the sigmoid colon, and normal rectal mucosa. We diagnosed the patient with diverticular colitis, and administered steroids and 5-aminosalicylic acid. Two months later, the inflammation and stricture were shown endoscopically to have improved.
