7/11/2023 0 Comments Spinal fluid leaking from nose![]() ![]() Runny nose and CSF leak are two medical conditions that cause rhinorrhea. Rhinorrhea can occur due to many reasons like cold temperatures, inflammatory (infections, allergies, and crying), non-inflammatory (head trauma), and other causes such as opioid withdrawal. Rhinorrhea is a condition that causes the free discharge of thin nasal mucus fluid. Most cases of traumatic otorrhea resolve spontaneously or with lumbar spinal drainage.The key difference between runny nose and CSF leak is that runny nose is a medical condition that occurs when mucus is being discharged out of the nose due to colder outer temperatures, flu, or allergies, while CSF leak is a medical condition that occurs when cerebrospinal fluid leaks from a hole in the outermost layer in the meninges (dura) and out through the nose or ear. Open surgical or endoscopic repair of anterior skull base leaks with rhinorrhea.The overwhelming majority of spontaneous leak patients have a spinal-level leak, although they are generally higher than the lumbar level. Surgical repair may be performed in patients with failed epidural blood patches if the site of the leak has been identified.Blood patches are generally thought to be safe but occasional reports of increased CSF pressure and persistent epidural fluid collections have been reported. An epidural blood patch is used in patients with spinal leaks who fail noninvasive measures.The pattern of hearing loss may resemble that of Meniere’s disease. Hearing testing is sometimes affected by CSF-leak. ![]() Spinal fluid testing with a beta-trace protein assay.Head or spine MRI to detect evidence of sinking of the brain, collapse of the superior opthalmic vein, subdural fluid collection, decrease in ventricular size and prominent dural sinuses, extra-arachnoid fluid, meningeal diverticuli, meningeal enhancement, or engorgement of epidural venous plexi.Head CT with reconstructive views to view skull base fracture anatomy.Tests not requiring lumbar puncture include: This study is somewhat invasive, requiring injection of material into the spinal canal. Radioisotope cisternography characteristically shows a decrease or absence of activity over the cerebral convexities and early accumulation of radioisotope in the bladder.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.Cerebrospinal Fluid (CSF) depletion may be caused by a leak, a shunt, inadequate production or too-rapid absorption. ![]()
