Secondary NPH can affect persons of any age and occurs due to conditions such as subarachnoid hemorrhage, meningitis, brain surgery, brain radiation, or traumatic brain injury. [16] These conditions are thought to lead to increased inflammation of the arachnoid granulations , which further leads to decreased CSF reabsorption and therefore ...
Normal pressure hydrocephalus (NPH) most often occurs in elderly patients with symptoms including gait disturbance, urinary incontinence, and cognitive issues. [33] It is commonly divided into two categories, idiopathic NPH (with unknown cause) and secondary NPH (due to trauma, hemorrhage, etc.).
A cerebral shunt is a device permanently implanted inside the head and body to drain excess fluid away from the brain. They are commonly used to treat hydrocephalus, the swelling of the brain due to excess buildup of cerebrospinal fluid (CSF).
CSF flow can be used in diagnosing and treating aqueduct stenosis, normal pressure hydrocephalus, and Chiari malformation. [6] Aqueduct stenosis is the narrowing of the aqueduct of Sylvius which blocks the flow of CSF, causing fluid buildup in the brain called hydrocephalus.
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
Normal pressure hydrocephalus Brain atrophy Preferable projection: Coronal plane at the level of the posterior commissure of the brain. Modality in this example: CT: MRI: CSF spaces over the convexity near the vertex (red ellipse ) Narrowed convexity ("tight convexity") as well as medial cisterns: Widened vertex (red arrow) and medial cisterns ...
