Insulinoma is a rare disease presenting with episodic neuroglycopenic and/or adrenergic symptoms. We describe the clinical case of a female subject, 44 years old, affected with insulinoma, misdiagnosed for two years as epilepsy, threaten with antiepileptics. Insuli-noma was diagnosed based on fasting blood glucose level of 15 mg/dl, high fasting immunoreactive insu-lin/blood glucose ratio (more than 0.3), and a tumor in the pancreas by abdominal CT. After surgical re-moval of the neoplasm, the blood glucose level and insulin level turned normal. A benign insulinoma was also confirmed by histopathological evaluation. The patient remained seizure-free during the 2-year follow up.
