Rare pediatric insulinoma case diagnosed by endoscopic ultrasonography: insights into endogenous hyperinsulinemic hypoglycemia

Insulinoma should be considered in cases of hypoglycemia triggered by fasting or exercise due to its intermittent insulin secretion. Given the small size of the pancreas and the anatomical differences in children, EUS is a highly sensitive diagnostic tool for detecting small pancreatic tumors, such as insulinoma.
