Radiologic studies are also useful however, they may be impractical if one does not know the level of the leak.Radioactive label or a fluorescent dye injected into the spinal fluid to test for the label or dye in the fluid.There is some danger of exacerbating an existing leak or causing a new one leak with a lumbar puncture, and the risks/benefits must be carefully considered. In this situation, leaks may recur until the cerebral ventricles are shunted. Other conditions to exclude when considering the diagnosis of CSF leak are orthostatic hypotension (which can cause dizziness on standing), positional vertigo due to inner ear disturbances, and orthostatic tremor.ĬSF leaks can also result from high-pressure hydrocephalus. CSF leaks have been reported due to cervical bone spurs. Speculatively, it would seem possible that CSF leaks might occur after whiplash injury, as frequently there are persistent similar symptoms without findings on other studies. Spontaneous leaks from the nose are uncommon. In this case, the leak is at the site of the puncture. CSF leaks can also occur in the nose after trauma or surgery.ĬSF leaks may follow diagnostic or therapeutic lumbar puncture as well as spinal anesthesia and after an inadvertent puncture of the dura following epidural anesthesia or epidural steroid injections. Sometimes they are unintentional consequences of an overdraining CSF shunt, placed for CSF hypertension. Spontaneous leaks are most commonly at the level of the spine, particularly the thoracic spine and cervicothoracic junction. Traumatic CSF leaks are usually present following basilar skull fractures with either leakage from the nose (rhinorrhea) or ear (otorrhea). It seems likely that these cases are often missed. Symptoms from the leak can be delayed for as long as a month. These symptoms are rather nonspecific as they are commonly encountered in migraine and post-traumatic headache.Ĭognitive decline has also been noted. Change in hearing (hearing loss of CSF leak likely results from lowering of CSF pressure, which lowers inner ear pressure).Headaches, which are more severe in the upright position and are alleviated by lying down with the head lower than the chest.Therapeutic nontargeted and targeted epidural blood and fibrin patching are performed under CT guidance by our expert CSF leak neuroradiology faculty.įor an evaluation by the Neuroradiology CSF Leak Team, please call (646) 962-5757.Cerebrospinal Fluid (CSF) depletion may be caused by a leak, a shunt, inadequate production or too-rapid absorption. We offer a full range of myelogram and cisternogram examinations utilizing all imaging modalities including CT, MRI, and fluoroscopy to identify the source of CSF leak. Our neuroradiology physicians work in close collaboration with neurosurgery and neurology to deliver the highest level of comprehensive care to our CSF leak patients. Our team of subspecialized, world-class Weill Cornell neuroradiologists are trained to identify the site (the dural tear) of cranial and spinal CSF leaks as well as treat spinal leaks with minimally-invasive, needle-based approaches. Patients can often go misdiagnosed or undiagnosed for many years. Spinal cerebrospinal fluid (CSF) leaks leading to intracranial hypotension can cause significant debilitation and an array of neurologic symptoms, most notably a positional headache, which worsens when upright and improves when lying down.
