摘要

Hypothalamic hamartomas (HH) are rare lesions of ectopic neural tissue arising from the wall of the hypothalamus. Patients with HH can present with gelastic seizures, precocious puberty or both. Seizures are usually progressive and accompanied by worsening behavioral problems and developmental delay.Stereotactic radiosurgery (SRS) has been shown to be safe and effective, resulting in improvement in seizures and halting tumor progression. Gamma Knife (GK) radiosurgery in the treatment of hypothalamic hamartoma has reported Engel Class 1 seizure status of up to 60%, with improvement in behavioral status in some cases2. Post-treatment magnetic resonance (MR) imaging as reported in the literature has not demonstrated significant changes within the treated areas of a HH.
