[Hypoglycemia associated with oral sulfonylurea hypoglycaemic agents in an 11-year-old girl].
In children more than 8 years old, hyperinsulinism is the most common cause of hypoglycemia.


METHODS
We report the case of an 11-year-old girl who presented recurrent hypoglycemia with endogenous hyperinsulinism (high insulin and C-peptide concentrations). The morphological investigations didn't find insulinoma. Finally the questioning identifies the voluntary intoxication with hypoglycemic agent. At a later date, the sulfonylurea dosage during an hypoglycaemic episode was positive.


CONCLUSIONS
The sulfonylurea drugs can mimic an endogenous hyperinsulinism and mislead the diagnostic to an insulinoma suspicion and lead to a surgical exploration. A sulfonylurea dosage should be done before planning out surgery.
