Objective: To investigate combined external ventricular drainage and endoscope-assisted microsurgery using the middle frontal gyrus approach in patients with severe ventricular hemorrhage with casting of the fourth ventricle and patients' recovery after this treatment.
Methods: Patients with severe ventricular hemorrhage with casting of the fourth ventricle (n = 41) were randomly assigned to intervention and control groups. Modified Graeb score was used to assess 3-day hematoma clearance rate before and after surgery, drainage tube extubation time for the 2 groups was compared, and time when blood clot in the fourth ventricle was not blocked with cerebrospinal fluid was compared. Glasgow Coma Scale was used to assess consciousness after surgery; Glasgow Coma Scale scores recorded 1 and 7 days after surgery were also compared. Modified Rankin Scale was used to evaluate patients' recovery 1 and 6 months after surgery. Hydrocephalus and intracranial infections in patients after surgery were recorded for 90 days.
Results: The 3-day hematoma clearance rate was dramatically higher in the intervention group. Modified Graeb score showed that more hemorrhage was delimited in 3 days in the intervention group. The intervention group exhibited significantly reduced length of block of the fourth ventricle and drainage tube extubation time. High Glasgow Coma Scale and modified Rankin Scale scores and significantly low incidence of complications (e.g., hydrocephalus and intracranial infection) were observed in patients in the intervention group.
Conclusions: Combined external ventricular drainage and endoscope-assisted microsurgery using the middle frontal gyrus approach can effectively improve severe ventricular hemorrhage with casting of the fourth ventricle and enhance patients' neurological function and recovery.

To research the value of Autostrain right ventricular (RV) technology in detecting and preventing right ventricular myocardial injury in patients undergoing breast cancer chemotherapy by providing an imaging basis for early identification. To examine the changes in various cardiac function parameters before and after chemotherapy, two-dimensional echocardiography was employed 48 h before chemotherapy, 48 h after the fourth cycle of chemotherapy, and 48 h after the eighth cycle of chemotherapy, respectively. The patients included those with breast cancer who underwent surgery and were primarily administered anthracycline-based chemotherapeutic drugs.

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.
