Ectopic pancreatic rest in a 35-year-old man presenting with gastrointestinal bleeding. Coronal T2-weighted MRI demonstrates a well-defined submucosal lesion along the prepyloric greater curvature of the stomach (arrow). The lesion parallels the signal intensity of the pancreas on the T2-weighted image. A few small cystic areas within the lesion were confirmed to be an anomalous dilated duct on pathology. Inset: coronal T1-weighted MRI reveals the lesion (arrow) to be mildly hyperintense on the T1-weighted image, again following the signal intensity of the pancreas.
