Insulinoma Associated with MEN1 Syndrome: A Case of Persistent Hypoglycemia in School-aged Child.

Insulinoma is a rare cause of non-ketotic hypoglycemia both in adults and in children. Pediatric patients account for approximately 5% of all cases, mostly due to isolated benign lesions, but it can also be part of a multiple endocrine neoplasia type 1 syndrome (MEN1). We report the case of a patient with multiple hospitalizations related to hypoglycemia and neuroglycopenia symptoms, with multiple studies demonstrating the presence of an insulinoma as part of the spectrum of MEN1 syndrome.
