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] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.

Some people with a sCSF leak have a chronic leak despite repeated patching attempts, leading to long-term disability due to pain and being unable to be upright, and surgery is often needed. The symptoms of a spontaneous CSF leak were first described by German neurologist Georg Schaltenbrand in 1938 and by American neurologist Henry Woltman of ...
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
The cause of this condition in terms of secondary empty sella syndrome happens when a tumor or surgery damages the gland, this is an acquired manner of the condition. [1] patients with idiopathic intracranial hypertension will have empty sella on MRI [5] The cause of primary empty sella syndrome is a congenital defect (diaphragma sellae) [6]
Decompressive surgery [5] involves removing the lamina of the first and sometimes the second or third cervical vertebrae and part of the occipital bone of the skull to relieve pressure. The flow of spinal fluid may be augmented by a shunt. The surgery may involve the opening of the dura mater to allow decompression of 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 ...
