Bilateral occipital dysplasia, seizure identification, and ablation: a novel surgical technique.
MRI-guided thermal ablation is a relatively new technique utilising heat to ablate both tumours and epileptogenic lesions. Its use against epilepsy offers some patients a new and relatively safe way of reducing or aborting seizures. Most cases of MRI-guided thermal ablation have been performed in patients with isolated lesions. Placement of depth electrodes prior to laser ablation has been rarely performed. We present a case with bilateral independent lesions traversing eloquent cortex, which, after sampling for seizures and successful ablation, retained normal function. The patient is, to date, seizure-free.
