A CSF leak is most often characterized by orthostatic headaches â headaches that worsen in a vertical position and improve when lying down. Other symptoms can include neck pain or stiffness, nausea, vomiting, dizziness, fatigue, and a metallic taste in the mouth (indicative of a cranial leak). A CT scan can identify the site of a cerebrospinal fluid leakage.
CSF Leak: A Curable Cause of Headache. Loss of the fluid that cushions and protects the brain may lead to intracranial hypotension, intense headaches. The most common cause of intracranial hypotension, or low cerebrospinal fluid (CSF) pressure in the brain, is CSF Leak. CSF cushions and protects the brain and spinal cord. It is held in place by a sac-like covering called the meninges. The thickest outer layer of the meninges is the dura. Normally, the brain floats in this fluid. A CSF leak is when a hole or tear in the dura allows this fluid to leak out.
