Summary
Asymptomatic heterotopic pancreas (HP) is a benign condition. Imaging can help differentiate HP from malignant masses, avoiding unnecessary surgery.
Area of Science:
- Gastroenterology
- Radiology
- Pathology
Background:
- Heterotopic pancreas (HP) is a rare congenital anomaly.
- HP can mimic neoplastic submucosal masses, leading to misdiagnosis.
- Distinguishing HP from gastrointestinal stromal tumors (GISTs) is clinically significant.
Purpose of the Study:
- To review gastric heterotopic pancreas (HP).
- To correlate imaging findings with pathologic findings.
- To aid in the diagnosis of gastric HP on computed tomography (CT).
Main Methods:
- Review of medical literature on gastric HP.
- Analysis of imaging features of HP on CT scans.
- Pathologic correlation of diagnosed HP cases.
Main Results:
- Asymptomatic HP is benign and requires no intervention.
- HP can be challenging to differentiate from malignant masses preoperatively.
- CT findings can suggest HP, guiding further diagnostic steps.
Conclusions:
- HP should be considered in the differential diagnosis of extramucosal gastric masses.
- Accurate diagnosis of HP can prevent unnecessary surgical resection.
- CT imaging plays a crucial role in the preoperative diagnosis of gastric HP.
