title: Ectopic pancreas: usual and unusual features.
abstract: Nine patients with ectopic pancreas in the stomach (8 patients) and duodenum (1 patient) were studied both radiographically and endoscopically. Correct diagnosis was made by radiography in six cases and by endoscopy in seven cases. Masses radiographically larger than 3 cm in diameter were seen in three patients. The incorrect radiographic diagnoses were related to the presence of a large mass in one patient and to the complications of severe bleeding and gastric outlet obstruction in the other two. Endoscopy and radiography are complementary modalities in the diagnosis of ectopic pancreas.
