GELASTIC SEIZURES TREATED BY RESECTION OF A HYPOTHALAMIC HAMARTOMA

A 7-year-old girl presented for evaluation of a peculiar kind of epilepsy. Her seizures began before 1 year of age and consisted of episodes of brief, uncontrolled and unprovoked laughter than with time progressed to include cursive, complex partial and generalized tonic-clonic seizures. Progressive impairment of cognitive functions was noted as well as precocious puberty. Neuroimaging examination disclosed a hypothalamic hamartoma. It was excised by a pterional approach, and no further seizures were noted. The authors propose direct surgery for the hypothalamic hamartoma as a treatment for this progressive syndrome.
