We report the case of a 72-year-old female who was admitted to our hospital because of obstructive colitis. Blood analysis showed her serum carcinoembryonic antigen (CEA) level to be 156.0 ng/mL. A sigmoidectomy and descending colostomy were performed for obstructive colitis due to colonic diverticulitis. Histopathological examination revealed active inflammation of the sigmoid colon without neoplasia. Her serum CEA level decreased within normal limits immediately after surgery.
