The authors demonstrate the utility of portable intraoperative CT scans for the rapid identification of ventricular catheter tip location after Ommaya reservoir placement. The O-arm (Medtronic Sofamor Danek, Memphis, TN, USA) was utilized to confirm ventricular catheter placement intraoperatively. Conventionally, a postoperative CT scan is obtained prior to Ommaya reservoir use to ensure proper catheter placement. By obtaining these images intraoperatively, revisions may be performed without the need for an additional surgical procedure, and the reservoir may be utilized immediately postoperatively.

Background: The study aimed to describe a new Ommaya reservoir implantation method in late-onset SMA patients, assessing its safety and effectiveness under standard clinical conditions.
Methods: Prospective observational study. Lumbar intrathecal access was unfeasible due to significant scoliosis and prior spinal surgeries with instrumentation.

Acute presentation of cystic craniopharyngioma is a potentially life-threatening condition, characterized by disability and increased mortality risk, often caused by large cysts with or without hydrocephalus. This study evaluated the applicability of minimally invasive neuroendoscopic surgery (NES) for rapid intracranial pressure relief and tumor control as an alternative to emergent microsurgical resection. A retrospective review of the electronic medical record database of patients with craniopharyngiomas treated at our institution between June 2007 and October 2024 identified 13 non-consecutive cases of acute presentation of cystic craniopharyngioma managed with NES.

CNS lymphoma is a rare form of non-Hodgkin lymphoma that primarily affects the brain, spinal cord, leptomeninges, or eyes, leading to severe neurological or ophthalmological complications. This case report details a 44-year-old male with human immunodeficiency virus and diffuse large B-cell lymphoma who experienced permanent vision loss due to optic perineuritis, a rare presenting symptom indicative of underlying CNS involvement. Despite previous remission, imaging revealed focal enhancements suggesting CNS lymphoma, highlighting diagnostic and management challenges in relapsed lymphoma, especially in immunocompromised patients.

Background: Cerebral autoregulation is a robust regulatory mechanism that stabilizes cerebral blood flow in response to reduced blood pressure, thereby preventing cerebral ischaemia. Scientists have long believed that cerebral autoregulation also stabilizes cerebral blood flow against increases in intracranial pressure, which is another component that determines cerebral perfusion pressure. However, this idea was inconsistent with the complex pathogenesis of normal pressure hydrocephalus, which includes components of chronic cerebral ischaemia due to mild increases in intracranial pressure.

Cerebrospinal fluid (CSF) has emerged as a valuable liquid biopsy source for glioma biomarker discovery and validation. CSF produced within the ventricles circulates through the subarachnoid space, where the composition of glioma-derived analytes is influenced by the proximity and anatomical location of sampling relative to tumor, in addition to underlying tumor biology. The substantial gradients observed between lumbar and intracranial CSF compartments for tumor-derived analytes underscore the importance of sampling site selection.
