Background: Ectopic pancreas is defined as a pancreatic tissue lacking vascular or anatomical continuity with the main body of the pancreas. The majority of cases are symptomatic; however, they can present with bleeding or luminal obstruction. Herein, we present a case that had ectopic pancreatic tissue in the mesentery of proximal jejunum mimicking gastrointestinal stromal tumor.
Case Presentation: We present a case of a 24-year-old Saudi female, married who presented to the emergency room because of lower central abdominal pain radiating to the flanks for 9 days with on-and-off fever, 1 day diarrhea, and urinary symptoms. She was conscious, coherent, afebrile, and ambulatory with vital signs in the Emergency room revealed an oral temperature of 36.5°C, heart rate of 81 bpm, respiratory rate of 18 per minute, BP of 121/75 mmHg, and SpO2 of 99%. Abdominal examination revealed soft and lax tenderness in the lower central abdomen and left flanks.
Conclusion: Ectopic pancreatitis should be taken into account in a patient who has chronic abdominal pain with a normal native pancreas according to imaging results. Small intestinal tumors, whether detected on imaging investigations or accidentally found after surgery conducted for another reason, should be diagnosed with ectopic pancreas in mind.
