Localized pseudomembranous colitis in the cecum and ascending colon mimicking acute appendicitis

摘要

A 61-year-old male was admitted to our hospital due to right lower abdominal pain and watery diarrhea for 3 d.Beginning 3 wk before he arrived in our hospital,he took 3 rd-generation cephalosporin(cefixime) for 2 wk due to chronic left ear otitis media.Colonoscopic examination revealed yellowish patches of ulcerations and swelling covered with thick serosanguineous exudate in the cecum and ascending colon.After 7 d of oral metronidazole treatment,his symptoms completely disappeared.We report a case of localized pseudomembranous colitis in the cecum and ascending colon mimicking acute appendicitis associated with cefixime.
