Craniospinal Hypotension

Share:

Craniospinal Hypotension is not an actual symptom of Superficial Siderosis. It presents as a secondary result of the traumatic event (accident or surgery) which caused your Superficial Siderosis. Craniospinal Hypotension is a condition caused by a dural leak of your cerebral spinal fluid. Your body produces spinal fluid every day, but if there is a leak, then your system may not be able to replace enough volume to support and cushion your brain. This low volume creates a negative pressure inside your brain cavity.

The signs of craniospinal hypotension are a postural headache, nausea, vomiting, neck pain, visual and hearing disturbances, and vertigo. Diagnosis is dependent on the postural component of a headache; pain increases or eases with positional changes of your head and body.

When symptoms are significant, the first choice is an epidural blood patch. In this procedure, some blood is taken from the patient’s arm vein and is injected into the spinal canal in the space outside the dura. Epidural patching sometimes involves the use of fibrin sealant. These procedures may be repeated several times if the improvement is incomplete or does not last.

If a blood patch procedure is not effective you may have to have a neurosurgeon attempt to close your dural defect with surgery. Your dural leaks location will not be identified in some cases but if surgery is successful in finding and closing the leak the headaches will stop.

Sources: Superficial siderosis is a rare neurologic disease characterized by progressive sensorineural hearing loss, cerebellar ataxia, pyramidal signs, and neuroimaging findings revealing hemosiderin deposits in the spinal and cranial leptomeninges and subpial layer. The disease progresses slowly, and patients may present with mild cognitive impairment, nystagmus, dysmetria, spasticity, dysdiadochokinesia, dysarthria, hyperreflexia, and Babinski signs. Additional features reported include dementia, urinary incontinence, anosmia, ageusia, and anisocoria. Superficial siderosis MedGen UID: 831707 •Concept ID: CN226971 •Finding Orphanet: ORPHA247245
