Intraprocedural Three-Dimensional Imaging Registration Optimizes Magnetic Resonance Imaging-Guided Focused Ultrasound and Facilitates Novel Applications.
Oper Neurosurg (Hagerstown)
November 2024
Department of Neurosurgery, University of Pennsylvania Health System, University of Pennsylvania Perelman School of Medicine, Philadelphia, Pennsylvania, USA.
Background And Objective: Transcranial magnetic resonance-guided focused ultrasound (MRgFUS) has revolutionized ablative treatment of essential tremor in recent years. However, limitations in precision targeting may account for suboptimal efficacy and significant side effects. We describe a simple intraprocedural three-dimensional image-guided lesion shaping technique that can improve overall outcomes of MRgFUS for essential tremor and facilitate expansion to novel indications.

Department of Clinical Neurological Sciences, Western University, London, ON. Canada; Department of Paediatrics, Western University, London, ON. Canada. Electronic address:
Objective: To conduct a systematic review on radiofrequency thermocoagulation (RF-TC) in pediatric epilepsy surgery. In addition, due to the low number of dedicated pediatric series, to conduct a pooled analysis of cases published in the literature.
Methods: We conducted a literature search using PUBMED and EMBASE which produced 432 results.
Stereoelectroencephalographic exploration and surgical outcome in Lennox-Gastaut syndrome.
Epilepsia
January 2025
Department of Epileptology and Cerebral Rhythmology, APHM, Timone Hospital, Marseille, France.
Objective: Lennox-Gastaut syndrome (LGS) is typically characterized by drug-resistant epilepsy and subsequent cognitive deterioration. Surgery is a rare but viable option for the control of seizures in a subset of patients with LGS. This study aimed to describe the organization of the epileptogenic zone network (EZN) in patients with LGS using stereoelectroencephalography (SEEG) and to report the outcome of post-SEEG treatment.

Epilepsia
January 2025
Department of Neuropediatrics and Muscular Disorders, Medical Center, Faculty of Medicine University of Freiburg, University of Freiburg, Freiburg im Breisgau, Germany.
Objective: Hypothalamic hamartomas (HHs) are associated with pharmacoresistant epilepsy. Stereotactic radiofrequency thermocoagulation (SRT) shows promise as a disconnecting intervention. Although magnetic resonance imaging (MRI) is typically used to determine the attachment and intervention side, it presents challenges in cases of bilaterally attached HH, where the epileptogenic side is unclear.

Fourth ventricular hamartoma (FVH) is a rare cause of HFS with only 5 cases reported in literature. While Gamma-knife radiosurgery (GKRS) has been used to treat hypothalamic hamartomas, this is the first case of FVH treated with primary GKRS.
