BACKGROUND: Treatment strategies for deep intracranial gliomas remain limited to stereotactic biopsy in many cases due to the morbidity of aggressive surgical resection. Since no cytoreductive therapy is offered, outcomes have been demonstrably poor compared to patients who are able to undergo primary surgical resection. OBJECTIVE: To present our practice, in an effort to reduce morbidity and still offer cytoreductive treatment, of offering the possibility of laser interstitial thermal therapy (LITT) for the primary treatment of intracranial deep gliomas that would be otherwise unamenable for resection...

OBJECTIVE: Magnetic resonance (MR)-guided stereotactic laser amygdalohippocampectomy is a minimally invasive procedure for the treatment of refractory epilepsy in patients with mesial temporal sclerosis. Limited data exist on post-ablation volumetric trends associated with the procedure. METHODS: 10 patients with mesial temporal sclerosis underwent MR-guided stereotactic laser amygdalohippocampectomy. Three independent raters computed ablation volumes at the following time points: pre-ablation (PreA), immediate post-ablation (IPA), 24 hours post-ablation (24PA), first follow-up post-ablation (FPA), and greater than three months follow-up post-ablation (>3MPA), using OsiriX DICOM Viewer (Pixmeo, Bernex, Switzerland)...

Anterior two-thirds corpus callosotomy is a common palliative surgical intervention most commonly employed in patients with atonic or drop seizures. Recently, stereotactic laser ablation of the corpus callosum without a craniotomy has shown promise in achieving similar outcomes with fewer side effects and shorter hospitalizations. The authors demonstrate ablation of the anterior two-thirds corpus callosum in a patient with Lennox-Gastaut syndrome and drug-resistant drop seizures. Technical nuances of laser ablation with 3 laser fibers are described...

Hypothalamic hamartomas (HHs) are benign lesions that cause medically refractory seizures, behavioral disturbances, and endocrine dysfunction. Open resection of HHs does not guarantee seizure freedom and carries a relatively high risk of morbidity. Minimally invasive stereotactic laser ablation has recently been described as an effective and safe alternative for HH treatment. Prior studies have not, however, assessed HH lesion size and morphology, 2 factors that may influence treatment results and, ultimately, the generalizability of their findings...

BACKGROUND: A stereotactically placed laser fiber can deliver thermal energy to an epileptogenic focus in the brain. This procedure is done under intraoperative (thermography) magnetic resonance imaging (MRI) guidance. Thermoablation can lead to edema in the surrounding area and can cause a secondary insult. In this report of 3 cases, we have quantified the edema produced after laser ablation by sequential MRI in the immediate postoperative period. CASE DESCRIPTIONS: Three patients with intractable epilepsy underwent a detailed neurologic and neuroradiologic workup to localize the site of epileptogenic foci...

INTRODUCTION: Treatment options for hypothalamic hamartoma (HH) include microvascular surgery, stereotactic radiofrequency thermocoagulation (SRT), laser interstitial thermal therapy, or Gamma Knife surgery. During SRT, thermographic monitoring cannot be performed and therefore highly accurate placement of electrode and confirmation of its position are required. We have used robotic guidance (ROSA) and coregistered it with O-arm for performing ablation of hamartoma. METHODS: Five patients with HH and gelastic seizures underwent SRT...

OBJECTIVE Stereotactic laser ablation and neurostimulator placement represent an evolution in staged surgical intervention for epilepsy. As this practice evolves, optimal targeting will require standardized outcome measures that compare electrode lead or laser source with postprocedural changes in seizure frequency. The authors propose and present a novel stereotactic coordinate system based on mesial temporal anatomical landmarks to facilitate the planning and delineation of outcomes based on extent of ablation or region of stimulation within mesial temporal structures...

The authors describe the case of a 22-month-old boy who presented with gelastic seizures and developmental delay. Magnetic resonance imaging and video-electroencephalography monitoring revealed a primarily intraventricular hypothalamic hamartoma and gelastic seizures occurring 20-30 times daily. The patient was treated with various regimens of antiepileptic medications for 16 months, but the seizures remained medically intractable. At 3 years of age, he underwent stereotactic laser ablation with an aim of disconnection of the lesion...
