Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine.They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium.

In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm.
Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] 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 ...
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
During World War II, Tarlov researched the use of blood plasma clotting agent as an adhesive to repair nerve cells. [2] Tarlov first noticed the cysts while doing a postmortem examination of 30 filum terminale specimens in 1938, and he published his findings in the Archives of Neurology & Psychiatry. He initially believed the cysts were the ...
[1] [18] The compression of these spinal nerve roots that control sensation and movement in the lower body results in the tingling, pain and weakness NC patients often experience. However, because the severity of symptoms does not correlate well with the degree of stenosis and nerve root compression, a clear understanding of the specific ...
Pudendal nerve entrapment is an example of nerve compression syndrome. Pudendal neuralgia ( PN ) refers to neuropathic pain along the course of the pudendal nerve and in its distribution . This term is often used interchangeably with pudendal nerve entrapment .
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
