A single, large diverticulum of the transverse colon was found by contrast enema (Fig. 1a). An abdominal computed tomography showed a 21.4 x 8.4-cm air-filled structure originating from the transverse colon that was filled with contrast material indicating the possibility of a fistulous tract between the stomach and transverse colon (Fig. 1b and c).
