Intracranial Hypotension

Intracranial hypotension is a condition in which there is negative pressure within the brain cavity.

From an evolutionary standpoint, as we became bipedal, certain accommodating mechanisms developed to prevent during upright positioning the overdrainage of fluid (CSF or blood) from the cranial to the spinal compartment, which could lead to intracranial hypotension.

Cerebrospinal fluid leak from the spinal canal:

A leak following a lumbar puncture (spinal tap).

A defect in the dura

Sometimes following exertion such as swinging a golf club.

A congenital weakness.

Following spinal surgery.

Following spinal trauma.

Following a shunt procedure for hydrocephalus.

Lumboperitoneal shunt.

Ventriculoperitoneal shunt with a low pressure valve.

In some cases, spinal CSF leaks can lead to a descent of the cerebellar tonsils into the spinal canal, similar to a Chiari malformation.

Large spinal dural defects can lead to herniation of the spinal cord into the defect.

If the cause of the intracranial hypotension can be identified, the outcome following treatment is typically excellent.
