Figure 2 Isolated form of cystic dystrophy of the duodenal wall. Arterial phase. Coronal view. A: Deformation and thickening of the medial wall of the duodenum (D), major papilla surrounded by well-defined cysts located in the submucosa (DD). The gastroduodenal artery is shifted forward and to the left, lying in the groove between the unaffected pancreatic head (P) and duodenal wall; B: Unchanged orthotopic pancreas. Only the duodenum and the groove are involved. SMA: Superior mesenteric artery; GDA: Gastroduodenal artery; RGEA: Right gastro-epiploic artery.
