The aim of this study was to investigate the structural and functional changes in the visual cortex in patients with suprasellar tumor with recovery of visual field defects at different times before and after surgical decompression of the optic nerves. ⋯ The postoperative visual improvement can be reflected in the increased GMV and ALFF of the bilateral pericalcarine cortex at 1 month postoperation, which suggests that an experience-dependent plasticity of the visual cortex was induced by an increase in sensory input.

The preventable shunt revision rate (PSRR) was recently introduced in pediatric hydrocephalus as a quality metric for shunt surgery. We evaluated the PSRR in an adult hydrocephalus population. ⋯ The 90-day PSRR can be applied to an adult population and serve as a quality metric.

The transradial approach has slowly been gaining momentum in neuroendovascular procedures. We sought to assess its feasibility and safety and present a case series of transradial intraoperative angiography (IOA) during microsurgical clip ligation of intracranial aneurysms. ⋯ Our initial experience shows the transradial approach for IOA in clip ligation of aneurysms to be feasible and safe, with potential advantages over transfemoral IOA.

To date, only a few documented cases exist of complete or near-complete paraplegia of the lower extremities following collapse of a vertebral body secondary to an aneurysmal bone cyst. We describe the preceding symptoms associated with this catastrophic event along with surgical management and recovery. ⋯ The unique combination of back pain and posture change symptoms in an otherwise healthy pediatric patient should heighten clinical suspicion for a possible aneurysmal bone cyst of the spine when formulating a differential diagnosis. Additionally, despite the clinical severity at presentation, patients may still experience significant recovery following expeditious surgical intervention.

Overshunting-Associated Myelopathy Treated with Endoscopic Third Ventriculostomy: A Case Report.
Overshunting-associated myelopathy (OSAM) is a rare complication of cerebrospinal fluid shunt placement. Previous reports have recommended removal or ligation of the shunt and use or revision of a pressure programmable valve to treat OSAM. We present a rare case of OSAM successfully treated with endoscopic third ventriculostomy (ETV). ⋯ This is the first case of OSAM treated with ETV. ETV might be a useful treatment option for OSAM after treatment for obstructive hydrocephalus.
