ulcer of the duodenal bulb.

4. • Fig GI 17-2 Feeding gastrostomy tube (open
arrow) prolapsed into the duodenal bulb. The
tube could be mistaken for a polyp on a large
stalk (solid arrows).

Barium study. (B) Cholangiogram.

10. • Fig GI 17-8 Pancreatic pseudocyst extending
into the wall of the duodenum and producing
a large intramural filling defect (arrows).

11. • Fig GI 17-9 Duodenal varices (arrows).

12. Fig GI 17-10 Intramural duodenal hematoma. The sharply defined
intramural mass (arrows) obstructs the lumen in the immediate
postbulbar area.

13. • Fig GI 17-11 Villous adenoma. Large mass at the
junction of the second and third portions of the
duodenum. The irregular surface of the mass (arrows),
with its crevices filled with barium, is characteristic of a
villous tumor.26
