Robot-assisted laser interstitial thermal therapy for drug-resistant epilepsy in hypothalamic hamartoma.

Hypothalamic hamartomas are congenital lesions of the hypothalamus, with a range of symptoms defined by lesion location. Common presenting symptoms include gelastic seizures and precocious puberty. When hamartoma-related seizures become resistant to medications, laser interstitial thermal therapy (LITT) has been shown to be an effective treatment. The authors present a case of robot-assisted LITT for a patient with an 11-year history of epilepsy due to hypothalamic hamartoma. In addition, they demonstrate the use of a stereotactic biopsy needle implemented during the procedure for possible biopsy of deep cranial lesions.
