Insulinoma is a functional endocrine tumor of the pancreas that secretes insulin. Insulinoma comprises 25% of the pancreatic endocrine tumors. Patients may have heterogeneous presentation of symptoms varying from mild autonomic symptoms to severe hypoglycemic episodes. Sometimes, insulinoma may present with neuropsychiatric symptoms which can be mistaken for seizure disorder or dissociative disorder. Careful evaluation of the patient with such symptoms is advised to avoid delay in diagnosis of Insulinoma.
