Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [2]
A shunt is described as a tube, ... (IIH) and pseudotumor cerebri (PTC), idiopathic intracranial hypertension is the preferred name for the condition. ...
Which can result in a variety of neurological symptoms, such as pseudotumor cerebri, chronic fatigue syndrome, different types of headaches, visual disturbances, pulsatile tinnitus and various neurodegenerative diseases.

The location of the shunt is determined by the neurosurgeon based on the type and location of the blockage causing hydrocephalus. All brain ventricles are candidates for shunting. The catheter is most commonly placed in the abdomen but other locations include the heart and lungs. [10] Shunts can often be named after the route used by the ...
A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...
Raised intracranial pressure, if severe or threatening vision, may require therapeutic lumbar puncture (removal of excessive cerebrospinal fluid), or neurosurgical treatment (optic nerve sheath fenestration or shunting). [3] Venous stenting is emerging as a minimally invasive, safer alternative to shunting. [21]
Neurohydrodynamics investigates the role of intracranial fluid hydrodynamics (e.g. cerebrospinal fluid, cerebral blood flow, and interstitial fluid) in the pathophysiology of neurological disorders such as hydrocephalus, Chiari malformation, syringomyelia, pseudotumor cerebri, cerebral vasospasm, Alzheimer's disease, multiple sclerosis and ...
Idiopathic orbital inflammatory (IOI) disease refers to a marginated mass-like enhancing soft tissue involving any area of the orbit.It is the most common painful orbital mass in the adult population, and is associated with proptosis, cranial nerve palsy (Tolosa–Hunt syndrome), uveitis, and retinal detachment.
