• Fig GI 10-1 Hyperplastic polyps. Multiple smooth filling defects of similar sizes.

• Fig GI 10-2 Adenomatous polyp. A long, thin pedicle (arrows) extends from the head of the polyp to the stomach wall.

• Fig GI 10-3 Leiomyoma of the fundus (arrow).

• Fig GI 10-4 Carcinoma of the stomach. A huge ulcer is evident in the smooth, fungating polypoid mass (arrows).

– Fig GI 10-5 Lymphoma. Multiple ulcerated, polypoid gastric masses (arrows).

• Fig GI 10-6 Leiomyosarcoma. There is scattered ulceration in this bulky tumor.

Fig GI 10-7 Ectopic pancreas. Central opacification (white arrow) of a rudimentary pancreatic duct in a soft-tissue mass (black arrows) in the distal antrum.

• Fig GI 10-8 Alcoholic gastritis. Multiple nodular filling defects (suggesting polyps) are due to enlarged gastric folds viewed on end.

• Fig GI 10-9 Glue bezoar in a young model-airplane builder. The smooth mass simulates an enormous air bubble.

• Fig GI 10-10. Peptic ulcer disease. There are innumerable small mucosal and submucosal polypoid masses, several of which contain ulcer craters (arrow).21

• Fig GI 10-11 Peptic ulcer disease. (A) Large incisura (black arrow) simulating a filling defect on the greater curvature. The incisura is incited by a long ulcer (white arrows) on the lesser curvature. (B) Double pylorus. The true pylorus and the accessory channel along the lesser curvature are separated by a bridge, or septum, that produces the appearance of a discrete lucent filling defect (arrow).

• Fig GI 10-12 Normal Nissen fundoplication. The distal esophagus with normal mucosal pattern (closed arrows) passes through the fundal pseudotumor (open arrows).22
