Enhanced CT and CT virtual endoscopy in diagnosis of heterotopic pancreas

Figure 2 Heterotopic pancreas in the gastric antrum of a 68-year-old woman; the lesion is protruding into the stomach cavity. This heterotopic pancreas is of lower density than the pancreas, is heterogeneous, and slightly enhanced. In both the axial (A) and sagittal images (B), there is a low-density strip (white arrow) in the center of the lesion, which may represent the duct of the heterotopic pancreas. From the sagittal image (B), it can be seen that although the heterotopic pancreas tissue lies in the gastric antrum wall, the wall is still well defined. This suggests that the lesion does not violate the surrounding tissues and organs.
