Abstract
A 61-year-old man presented to our hospital with a two-week history of fever and lower abdominal pain. On physical examination, lower abdominal tenderness was found. Laboratory tests showed elevated white blood cell count and C-reactive protein level. Abdominal computed tomography demonstrated diffuse thickening of the walls of the sigmoid colon and rectum. Colonoscopy revealed mucosal edema and multiple white spots at the sigmoid colon and rectum. After performing biopsy of the white spots, we observed discharge of pus. Pus discharge was also observed at the dark red rectal mucous membrane. We made a diagnosis of phlegmonous colitis. The patient was cured by antibiotic treatment and was discharged from the hospital on the 27th day.
