Multiple endocrine neoplasia type 1 presenting with refractory seizures.

We report a case of 29-year-old woman referred to us for management of refractory epilepsy. Under observation, she was detected to have recurrent hypoglycaemia during the episodes of seizures. On investigation, she was found to have hyperinsulinemic hypoglycaemia. Her triple-phase CT scan of abdomen showed neuroendocrine tumour of pancreatic head, with bilateral renal calculi. Screening of other endocrine glands revealed pituitary microadenoma and parathyroid adenoma on imaging, which was also supported by biochemical and hormonal profile. On the basis of tumours involving parathyroid, pancreatic islets and pituitary gland, she was diagnosed as a case of multiple endocrine neoplasia type 1. Pancreatic tumour removal was done and bromocriptine was started. She was followed up for 6 months postoperatively and never had seizures even without antiepileptic drugs. This case report highlights an exceptional treatable cause of uncontrolled seizures.
