title: Insulinoma--a deceptive endocrine tumour.
abstract: Insulinoma is a deceptive endocrine tumour that can easily mislead even an astute clinician because of its bizarre and nonspecific symptom complex. A 45 year old woman presented with altered behaviour, seizures and spells of coma and was being treated as a case of hysterical neurosis. Biochemical and radiological investigations revealed fasting hypoglycaemia, endogenous hyperinsulinism, and a pancreatic parenchymal lesion. Removal of the pancreatic lesion resulted in abrupt restoration of euglycaemia and complete disappearance of patients' symptoms.
