Summary
A patient with Zollinger-Ellison syndrome had a gastrinoma located in a celiac lymph node, not the pancreas, as initially suspected. Surgical removal of the lymph node and a duodenal nodule normalized gastrin levels.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endocrinology
Background:
- Zollinger-Ellison syndrome is characterized by elevated gastrin levels due to a gastrinoma.
- Accurate localization of the primary tumor is crucial for effective treatment.
- Imaging modalities can sometimes be inconclusive in identifying the exact tumor location.
