May 28, 2018 · From the fourth ventricle the CSF drains in the openings (foramina) into the subarachnoid space surrounding the brain and spinal cord. CSF is absorbed in the arachnoid villi. Blockage of CSF flow anywhere in the ventricular system produces obstructive hydrocephalus.

Anatomical Diagrams - These diagrams show the anatomy of the brain, the ventricles, and the spine.

There are two main forms of hydrocephalus in adults: acquired hydrocephalus and normal pressure hydrocephalus (NPH). People with NPH experience a build-up of CSF in their brains without necessarily experiencing a significant increase in pressure. Cerebrospinal fluid (CSF) is a clear, colourless fluid that surrounds the brain and spine.

Schematic view of four different types of hydrocephalus described in the literature by the terms asymmetric hydrocephalus, isolated lateral ventricle, isolated unilateral hydrocephalus,...

Feb 23, 2025 · Hydrocephalus denotes an increase in the volume of CSF, causing the distension of cerebral ventricles (ventriculomegaly) due to insufficient passage of the CSF from its point of production in the ventricles into the systemic circulation, whether that be via resorption into the dural venous sinuses or via the glymphatic pathway 7.

Patients with hydrocephalus are typically treated with an implanted shunt system that relieves the increased intracranial pressure from the CSF accumulation ( Figure 1). ... View in full-text ...

Normal pressure hydrocephalus (NPH) is a potentially reversible syndrome characterized by enlarged cerebral ventricles (ventriculomegaly), cognitive impairment, gait apraxia, and urinary...

Assess neurological satus e.g motor, sensory, eye movement and mental state. Examine pupil for change in size and shape. Measuring head circumference and appearing of fontanelles. …

Hydrocephalus is caused by an imbalance between how much cerebrospinal fluid is produced and how much is absorbed into the bloodstream. Cerebrospinal fluid is produced by tissues lining the ventricles of the brain. It flows through the ventricles by way of interconnecting channels.
