Symptoms of leak or improper levels of cerebrospinal fluid include: Headaches, especially when standing. This study shows that early treatment of a ventral spinal CSF leak offers a unique opportunity to prevent neurologic disability from superficial siderosis and bibrachial amyotrophy. Some patients also report symptoms after experiencing whiplash, and leaks have been known to develop when caused by the development of spinal bone spurs. None of the patients developed spinal cord herniation.Īmong patients with SIH and a persistent ventral spinal CSF leak, the risk of developing serious long-term sequelae is considerable. The probability of these complications increased from 0% at 48 months to 4.5% (95% confidence interval 1.0%-28.0%) at 56 months, 10.5% (95% CI 3.0%-36.4%) at 96 months, 32.7% (95% CI 15.0%-62.8%) at 144 months, and 57.9% (95% CI 30.2%-87.6%) at 192 months. Any tear or hole in the membrane that surrounds the brain and spinal cord (dura) can allow the fluid that surrounds those organs to leak. The patient population consisted of a consecutive group of patients with SIH and persistent ventral spinal CSF leaks who were first seen within 1 year of onset of SIH symptoms and who had at least 1 year of follow-up.Īmong 51 patients with SIH and a persistent ventral spinal CSF leak, superficial siderosis developed in 6 patients and bibrachial amyotrophy in 2 patients during 280 patient-years of follow-up. This imaging test uses a contrast agent, gadolinium, to better highlight abnormalities in the brain or spine that result from a. Tests to diagnose a spinal CSF leak may include: MRI with gadolinium. The flexibility of your joints also may be checked. This cohort study was conducted using data from a prospectively maintained database of patients who meet the modified International Classification of Headache Disorders, 3rd edition criteria for SIH. Although the hole made by a spinal needle is exceptionally small, in some people this can still lead to leakage of CSF. Your doctor will likely start with your medical history and a physical exam. We undertook this study to determine the risk of these serious complications of persistent ventral spinal CSF leaks. Intracranial hypotension is a rare condition, and about 5 people out of every 100,000 have it. Therefore, CSF leak is an extremely important entity to detect and treat. That causes a condition known as intracranial hypotension (intracranial means inside your skull and hypotension means lower than normal pressure). Cerebrospinal fluid (CSF) leakage denotes a compromise in the integrity of the central nervous system and predisposes it to environmental stressors like infections and direct injury to the parenchyma, which hampers its normal functioning. ![]() However, the risk of developing such sequelae has not been established in this population. Having a CSF leak causes a drop in fluid pressure inside your head. ![]() Superficial siderosis, bibrachial amyotrophy, and spinal cord herniation are unusual but serious long-term sequelae of persistent spontaneous spinal CSF leaks in patients with spontaneous intracranial hypotension (SIH), particularly ventral spinal CSF leaks. The symptoms of a CSF leak include fluid drainage from the ears or nose and a headache that worsens when the head is upright.
