The insular cortex is an eloquent island of mesocortex surrounded by vital structures making this region relatively challenging to neurosurgeons. Historically, lesions in this region were considered too high risk to approach given the strong chance of poor surgical outcome. Advances in recent decades have meant that surgeons can more safely access this eloquent region. Seizure outcome after excision of insular low-grade gliomas is well reported, but little is known about seizure outcomes after excision of insular high-grade gliomas. ⋯ Excision of insular high-grade gliomas is safe and results in excellent postoperative seizure control.

Placing the patient in lateral position is an option for implantation of stereoelectroencephalography (SEEG) electrodes that have a posterior entry point. Previous studies reported the accuracy of SEEG electrodes but not specifically in relation to position. The aim of this study was to analyze accuracy of SEEG electrodes by position. ⋯ SEEG leads implanted in lateral position exhibit an accuracy and safety profile in accordance with previous studies. In this cohort, target error was smaller in the lateral position, particularly in noninsular electrodes.

To identify the apical vertebra is relate to the occurrence of vertebral rotatory subluxation (VRS) in degenerative lumbar scoliosis. ⋯ VRS is an important characteristic to consider in degenerative lumbar scoliosis that can affect the coronal and sagittal alignment. The apical vertebra is correlated with the occurrence of VRS; an apical vertebra translation greater than 23.2 mm and apical vertebra tilt angle greater than 11.8° are highly correlate with the occurrence of VRS.

Increasing restrictions over trainees' working hours and the recent coronavirus disease 2019 pandemic warrant new educational methods of surgical skills. We assessed a novel video-recording system for neuroendovascular skill education, developed with the installation of a hybrid operating room (OR) at our institution. ⋯ Our "selfie" video recording system was useful for skill training of neuroendovascular interventions.

Giant aneurysms of the intracranial vertebral artery and posterior inferior cerebellar artery are challenging to treat as they often necessitate direct sacrifice of the diseased segment, which is thought to carry high morbidity due to brainstem and cerebellar stroke. Here, we report images of twin giant aneurysms of the left posterior inferior cerebellar artery at the brainstem and cerebellopontine angle region in a young child.
