Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and
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.
Spinal cord stroke is a rare type of stroke with compromised blood flow to any region of spinal cord owing to occlusion or bleeding, leading to irreversible neuronal death. [1] It can be classified into two types, ischaemia and haemorrhage, in which the former accounts for 86% of all cases, a pattern similar to cerebral stroke.
The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).
In adults, the spinal cord terminates around the level of the disc between L1 and L2, while in neonates it extends to L3 but can reach as low as L4. [16] Below the spinal cord there is a bundle of nerves known as the cauda equina or "horse's tail". Hence, lumbar epidural injections carry a low risk of injuring the spinal cord.
After suffering a stroke in 2012 at 22-years-old, Ms Rendulic was left with no mobility in her left hand as a result of chronic post-stroke muscle weakness. Stroke survivor moves hand for first ...
The extension of cellular immune response to the brainstem and spinal cord causes inflammation and necrosis of small meningeal vessels. [citation needed] In tertiary syphilis, reactivation of chronic latent infection may result in meningovascular syphilis, arising from endarteritis obliterans of small, medium, or large arteries supplying the CNS.
