Neuroendocrine tumor. Arterial phase CT (a, b) of a patient with type I multiple endocrine neoplasia, with hypergastrinemia, shows two small hypervascular nodular lesions on the wall of D2 and D1 (arrows). Coronal reformation (c) better shows the duodenal bulb lesion (arrow) and another similar lesion at the pancreatic head (arrowhead). Histopathological study following pancreatoduodenectomy revealed duodenal and pancreatic neuroendocrine tumors (gastrinomas). Abdominal CT of another patient shows a mass (arrows) in the medial wall of D2 with intense contrast enhancement in the arterial phase (d) and venous phase (e) of the dynamic study. The high spatial resolution provided by CT clearly shows that the lesion is independent from the pancreas
