Solid Pseudopapillary Neoplasm of the Pancreas Presenting With Gastric Outlet Obstruction

Solid pseudopapillary neoplasm (SPN) of the pancreas are rare tumors accounting for a minor portion of all exocrine pancreatic tumors. It usually occurs in young women. It has a very low malignant potential with a relatively indolent clinical course. A small subset of patients exhibits pathological features of malignancy. Herein, we present a rare case of pancreatic SPN that presented with gastric outlet obstruction. Despite the characteristic computed tomography (CT) findings, due to its rarity, it was missed in more common conditions such as gastrointestinal stromal tumors. In our case, we found that the tumor was causing extrinsic duodenal compression leading to gastric outlet obstruction, creating a diagnostic dilemma.
