Objective: To reduce postoperative hydrocephalus following surgery in the region of the fourth ventricle. METHOD/TECHNIQUE: We describe the use of a conventionally placed lateral ventricular catheter to facilitate anterograde ventricular irrigation during surgery in the region of the fourth ventricle. This technique offers a safe alternative to more conventional approaches to fourth ventricular irrigation and obviates the need for placement of a third or fourth ventricular catheter and/or serial lumbar punctures by thoroughly flushing blood and tissue debris from the operative field at the time of surgery.
Results: Preliminary results spanning a five-year period show a lower incidence in the need for early ventriculo-peritoneal shunts (5%) and delayed ventriculo-peritoneal shunts (10%).
Conclusion: This technique represents a safe method of reducing hydrocephalus following operative procedures in the region of the fourth ventricle.

The origins of resting-state functional MRI (rsfMRI) signal fluctuations remain debated. Recent evidence shows coupling between global cortical rsfMRI signals and cerebrospinal fluid inflow in the fourth ventricle, increasing during sleep and decreasing with Alzheimer's disease (AD) progression, potentially reflecting brain clearance mechanisms. However, the existence of more complex brain-ventricle coupling modes and their relationship to cognitive decline remains unexplored.

Introduction: The area postrema, located on the floor of the fourth ventricle, regulates vomiting, fluid balance, osmoregulation, and immunomodulation. First documented in 1896, it has been a subject of scientific interest ever since. Area postrema syndrome (APS) is characterised by intractable nausea, vomiting, or hiccups, typically associated with neuromyelitis optica spectrum disorder (NMOSD).

Background: This particular case is a world-first with no previous literature reports on patients presenting with both benign acoustic schwannoma and malignant ependymoma.
Case Presentation: A 60-year-old woman with unexplained right-sided hearing loss that had worsened progressively over 4 years, along with intermittent dizziness that had begun 3 years prior. Our preliminary diagnosis included: (1) Right acoustic neuroma; (2) Ependymoma of the fourth ventricle; and (3) Hydrocephalus.
Introduction Pediatric hemifacial spasm (HFS) is rare, presenting early in infancy, and often fraught with subsequent psychomotor and intellectual deficits. 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.

Prognosis is influenced by tumor grade, location, resection extent, and preoperative Karnofsky Performance Status Scale (KPSS) scores. This study evaluates clinical features, treatment outcomes, and factors affecting prognosis in patients with intracranial ependymomas.
