[A case of segmental colitis associated with diverticular disease].

Segmental colitis associated with diverticular disease (SCAD) is a colonic inflammatory disorder with localized non-granulomatous inflammation at sigmoid colon, and associated with colonic diverticulosis. SCAD is an apparently uncommon disorder in Western. We experienced a rare case of SCAD in a 46-year-old woman who visited the hospital due to abdominal discomfort. Colonoscopic examination showed multiple sigmoid diverticula in association with a segment length colitis. Colonoscopic biopsies of the sigmoid colon demonstrated cryptitis and crypt abscess along with chronic inflammatory cells infiltration. The biopsies of the rectum was histologically normal. The patient was given the diagnosis of SCAD and treated with oral mesalamine. This is the first case of SCAD reported in Korea.
