  Fig. 1. Imaging modalities for the pancreatic cystic lesion. (A) Abdominal computed tomography (CT) shows a well-defined cystic lesion measuring 2.1 cm at the neck of the pancreas, connected to the pancreatic duct. (B) Endoscopic ultrasound demonstrates an anechoic cystic lesion without solid content. (C) Pancreatography shows a connection of the cystic lesion (arrow) to the main pancreatic duct. (D) Follow-up CT shows no interval change in the size of the cystic lesion despite the long-lasting plastic stent.

  Fig. 2. Histopathologic examination of the resected pancreatic cystic lesion. (A) Gross examination shows a unilocular cyst containing serosanguineous fluid. (B-D) The surrounding solid component diagnosed with a grade 2 neuroendocrine tumor (B, ×12, hematoxylin and eosin [H&E]; C, ×400, H&E; D, ×200, synaptophysin).
