Colonic perforation by ingested chicken bone.

Abstract

59-year-old man with a history of colonic diverticulosis presented with severe left lower quadrant pain and fever of several days’ duration. Unenhanced radiography of the abdomen showed dilated loops of small bowel with air‐fluid levels more consistent with smallbowel obstruction rather than ileus. CT with oral and IV contrast material showed free intraperitoneal air, dilated loops of small bowel without a definite transition point, and sigmoid diverticulosis (Fig. 1A). The patient underwent resection of the involved segment of the sigmoid colon. Pathology revealed colonic perforation caused by a chicken bone in the setting of sigmoid diverticulitus (Figs. 1B and 1C).
