Summary

Stereotactic radiofrequency ablation can improve epilepsy in most patients with hypothalamic hamartomas. This minimally invasive treatment is most effective for small to medium-sized lesions, offering a potential solution for this challenging neurological condition.

Background:

Hypothalamic hamartomas are linked to progressive epileptic encephalopathy.
Non-invasive studies suggest lesion destruction or isolation may control seizures.

Purpose of the Study:

To evaluate the efficacy and safety of stereotactic radiofrequency ablation for hypothalamic hamartomas.
To assess the impact of lesion size on treatment outcomes.

Main Methods:

Patients underwent stereotactic radiofrequency ablation, with or without endoscopic assistance.
Outcomes were assessed based on seizure improvement and morbidity.

Main Results:

Epilepsy improved in 60% of treated patients.

The procedure was associated with minimal morbidity.

Treatment success was less pronounced in patients with large hypothalamic hamartomas.

Conclusions:

Stereotactic radiofrequency ablation is a viable treatment option for small to medium-sized hypothalamic hamartomas.
This minimally invasive approach offers seizure control with acceptable safety profiles.
