A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak. [6] [7] [8] A spontaneous spinal cerebrospinal fluid leak may occur sometimes in those with predisposing heritable connective tissue disorders including Marfan syndrome and Ehlers–Danlos syndromes.
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
Cerebrospinal fluid rhinorrhoea; Specialty: Neurology, neurosurgery, otorhinolaryngology,Oral and maxillofacial surgery: Symptoms: clear, colourless liquid draining from nose: Complications: infection: Causes: basilar skull fracture: Diagnostic method: brain scans, testing nasal discharge to see if it is CSF: Differential diagnosis: other types ...
The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks . [ 6 ] However, in many patients, dural ectasia is asymptomatic.

Kendra Jackson was diagnosed with a cerebrospinal fluid (CSF) leak that was caused by a minor car accident in 2013. One woman's chronic 'runny nose' was actually a brain fluid leak-here's what ...
Causes of this negative or pulling pressure include a tethered cord or an excessively tense Filum terminale, a cerebrospinal fluid leak creating a negative pressure around the spinal cord as the fluid surrounding the cord leaks out, or a CSF-venous fistula, in which the CSF leaks into a nearby vein.
