Аннотация
BACKGROUND: Radiosurgery has been advocated as a primary treatment for hypothalamic hamartoma (HH), but it has a risk of damaging the surrounding structures and does not have an immediate effect for refractory epilepsy, endocrinological and mental disorders.
METHOD: We report on a 13-year-old boy with a large and sessile HH who presented with intractable seizures, precocious puberty and aggressiveness. Stereotactic radiofrequency ablation (SRA) combined with an image fusion technique was performed to make a maximum ablative lesion within the HH via multiple trajectories.
FINDINGS: After surgery, we observed rapid cessation of the gelastic seizures and aggressiveness. The ophthalmological function did not get worse, and the hypothalamopituitary function improved.
INTERPRETATION: SRA in combination with an image fusion technique is a viable alternative treatment for HH, because it provides precise preoperative simulation and immediate improvement of symptoms can be obtained.
