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.

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 ...
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 ...
Signs and Symptoms. Radiculopathy is a diagnosis commonly made by physicians in primary care specialties, orthopedics, physiatry, and neurology. The diagnosis may be suggested by symptoms of pain, numbness, paresthesia, and weakness in a pattern consistent with the distribution of a particular nerve root, such as sciatica.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Sensory neuronopathy (also known as sensory ganglionopathy) is a type of peripheral neuropathy that results primarily in sensory symptoms (such as parasthesias, pain or ataxia) due to destruction of nerve cell bodies in the dorsal root ganglion. [1]
Among the signs/symptoms are the following (different symptoms are caused by different nerves, such as the foot drop caused by the peroneal nerve [4]): Other HNPP symptoms can include: Partial hearing loss and facial numbness (cranial nerves can be afflicted by HNPP), intolerable fatigue and pain, sensation loss and muscle weakness in the hands ...
Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (which in most cases is farther from the neuron's cell body) degenerates. [1]
