Abstract

Small bowel angioedema is a rare adverse effect of iodinated contrast medium. Here, we report the first case of contrast medium-induced small bowel angioedema with concurrent respiratory tract symptoms. A patient with colon cancer underwent CT scanning for preoperative staging. After injection of the contrast medium, a persistent cough developed and CT images showed that the small bowel wall was abnormally thickened. It returned to normal by the follow-up. The persistent coughing that developed right after the CT and small bowel wall thickening on the contrast-enhanced CT suggested the diagnosis of small bowel angioedema induced by the contrast medium.
