Invasive ductal adenocarcinoma arising from heterotopic pancreas in the jejunum: Case report and literature review.

Although the presence of pancreatic tissue outside of the usual anatomical location of the pancreas is not an uncommon incidental finding, the risk of malignancy is extremely low. We report a case of ductal adenocarcinoma arising within a focus of heterotopic pancreas, occurring in the jejunum of an 81 year old woman. The patient presented with a history of progressive gastrointestinal occlusive symptoms.

Dark-lumen MR colonography with fecal tagging: a comparison of water enema and air methods of colonic distension for detecting colonic neoplasms.

The purpose was to evaluate MR colonography (MRC) with barium fecal tagging in detecting colorectal pathology and to determine how air-based and water-based colonic distension influences MRC. We studied 83 patients with high risk of colonic neoplasms. All received oral barium sulfate for colonic preparation before unenhanced and enhanced T1-weighted gradient-echo MRC using either water (n=54) or air (n=29) for colonic distension.
