Specialists at Macquarie Neurosurgery & Spine are highly experienced in the management of CSF disorders, including CSF leak. When the dura mater (a connective tissue that holds CSF in around the spinal cord) has a tear, the result is a loss of CSF volume, known as intracranial hypotension. Cerebrospinal fluid (CSF) bathes and supports the brain and spinal cord. Although some mechanisms account for the CSF leakage have been elucidated, spinal canal stenosis has never been reported as a pathological cause of intracranial hypotension. In these cases, treatment may be more complex. Symptoms of a spinal CSF leak: From common to rare. Intracranial hypotension is a disorder characterized by low cerebrospinal fluid (CSF) pressure typically caused by loss of CSF. Where there is a delay in diagnosis, some patients with a CSF leak develop chronic symptoms and complications. Early diagnosis simplifies treatment and improves its chances of success. Usually it is contained in one area within the skull and down the spine, but. In more complex spinal cases, as well as cranial cases, neurosurgery may be required.ĬSF leaks (including spontaneous leaks) are more common than previously thought. Cerebral spinal fluid (CSF) is the fluid that bathes the brain and spinal cord. Alternatively, a surgical sealant (called fibrin glue) can be used to repair the defect. A minor procedure, called an epidural blood patch, may be used to seal a spinal leak. A combination of an underlying weakness of the. In other cases, a CSF leak will require more active intervention. Leakage of the spinal cerebrospinal fluid (CSF) is the most common cause of spontaneous intracranial hypotension. In many cases, a CSF leak will heal on its own. A CSF leak occurs when the CSF escapes through a tear or hole in the dura, the outermost layer of the meninges. CSF surrounds the brain and spinal cord, and is contained by a connective tissue membrane called the dura mater. Treatment includes strict bed rest, adequate fluid intake and caffeine. Cerebrospinal fluid leaks can also occur in the brain (cranial CSF leak), but these result in different symptoms than a leak in the spinal dura. They suggested it might be a spinal CSF leak caused by the procedure. In the present study, we identified 3 types of spontaneous spinal CSF leaks: the dural tear, the meningeal diverticulum, and the CSF-venous fistula. He leads a collaborative team of radiologists, neurologists, and neurosurgeons to provide cutting-edge testing and treatment for this condition.Initially, a CSF leak may be treated conservatively. Andrew Callen, is a neuroradiologist who specializes in diagnosingĪnd treating CSF leaks. In addition, a type of leak called a CSF-venous fistula (CVF) was only discovered in 2014, and requires specialized testing called dynamic myelography in order to diagnose.Īt the University of Colorado CSF Leak Program, our goal is to provide world-class, patient-centered, multidisciplinary care for patients who may be suffering from a spinal-fluid leak. Once considered to be a diagnosis made only in individuals with an abnormal brain MRI, we are now understanding that patients may or may not present with an abnormal brain MRI but still The understanding of SIH has greatly increased in the past decade.

In addition to headache, patients also often describe a sense of pressure, ringing in their ears, changes in vision or hearing, dizziness, forgetfulness, or personality Mainly by headache symptoms that are worse when upright and improved when lying flat. Treatment for spinal CSF leak varies from conservative measures to surgical procedures. SIH is a headache disorder caused by leakage of cerebrospinal fluid (CSF) from the spine, and is characterized

The University of Colorado CSF Leak Program specializes in the diagnosis and treatment of spontaneous intracranial hypotension (SIH). The purpose of this article is to review the imaging of spinal CSF. The myelographic appearance of the leaks may vary, however, depending on the cause of the leak, rate of leakage, and imaging modality used. Leak detection and localization are important for both diagnosis and treatment.
