Looking beyond the tract: an obscure cause of recurrent gastrointestinal bleeding

A 62-year-old man presented with anemia (hemoglobin level of 6.9 g/dL). He had 3 months history of intermittent painless melena. However, the underlying cause of the bleeding had not been identified despite extensive investigations, including upper gastrointestinal endoscopy, colonoscopy, and small bowel capsule endoscopy. Abdominal contrast-enhanced computed tomography showed a nonenhancing cystic lesion located at the pancreatic body measuring 10 mm in diameter. The cystic lesion was adjacent to the splenic artery and accompanied by upstream dilatation of the main pancreatic duct.
