Gastric outlet obstruction from pyloric ectopic pancreatic tissue: a teaching case

Ectopic pancreatic tissue at the pylorus, though rare, is a recognized cause of gastric outlet obstruction. This Eurorad teaching case highlights the CT and MRI features that help distinguish it from other submucosal masses.

• Single teaching case from ESR Eurorad; no systematic study.
• Imaging mimics include gastrointestinal stromal tumor and leiomyoma; ectopic pancreas demonstrates similar attenuation/signal to normal pancreas.
• Key limitation: based on a single case report, limiting generalizability.
