The utility of virtual and augmented reality based on functional neuronavigation and intraoperative magnetic resonance imaging (MRI) for glioma surgery has not been previously investigated. ⋯ Combining virtual and augmented reality based on functional neuronavigation and intraoperative MRI can facilitate resection of gliomas involving eloquent areas.

The caudal zona incerta (cZI) is an increasingly popular deep brain stimulation (DBS) target for the treatment of tremor-predominant disease. The dentatorubrothalamic tract (DRTT) is a white matter fiber bundle that traverses the cZI and can be identified using diffusion-weighted magnetic resonance imaging fiber tractography to ascertain its precise course. In this report, we compare 2 patient cases of cZI DBS, a responder and a nonresponder. ⋯ Preoperative diffusion-weighted magnetic resonance imaging fiber tractography imaging of the DRTT has the potential to improve and individualize DBS planning.

The purpose of this report is to describe the surgical methodology and effectiveness of minimally invasive oblique lumbar interbody fusion (OLIF) assisted by spinal endoscopy, which can treat disk herniation from the central to contralateral foramen. OLIF showed indirect decompression effects on reduction of spondylolisthesis and a foraminal widening effect on disk height restoration. ⋯ OLIF with spinal endoscopic discectomy can achieve neural decompression without additional posterior decompression and can be used as an alternative treatment in selected cases.

Case Reports
A traumatic spinal perimedullary arteriovenous fistula induced by a cervical glass stab injury.
In the literature, perimedullary arteriovenous fistula (AVF) is an uncommon spinal vascular malformation that is generally regarded as a congenital lesion. To our knowledge, only a few cases of traumatic perimedullary AVF have been reported in the literature so far. ⋯ Cervical trauma should be considered as a possible cause of de novo perimedullary AVF. Recognition of this phenomenon is important.

The Pipeline Embolization Device (PED) has been used and shown to be safe under monitored anesthesia care (MAC). We present the results of the first study, to our knowledge, assessing the safety and feasibility of same-day discharge in patients undergoing treatment with the PED, using MAC. ⋯ PED treatment under MAC is feasible and safe. This has brought forth an era of outpatient treatment of CAs where patients are discharged home 6 hours after the procedure.
