Transient angioedema of the small bowel due to intravenous nonionic iodinated contrast media

A 14-year-old girl was referred to our hospital for suspected accessory spleen torsion. There was no history of allergy or medication use. Abdominal multiphase contrast-enhanced computed tomography (CT) was performed. The patient had mild abdominal discomfort after intravenous administration of nonionic iodinated contrast media (CM) for CT. CT images in the arterial phase showed normal proximal small bowel (Figure 1A, B); however, CT images in the venous phase revealed that the proximal small bowel had circumferential thickening of the wall including the duodenum (Figure 2A, B).
