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.

If the cysts develop in critical areas of the central nervous system, they can present one or more of the following symptoms: [6] Pressure in the spinal cord or brain Rupture of nerves around the cyst; Weakness in specific parts of the body controlled by the cyst-infected brain region; Inflammation; Hydrocephalus [7] Brainstem hemorrhage ...
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
A neuron (also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signaling. Neurons are the core components of the brain, spinal cord, and peripheral nerves. Soma; Axon; Myelin; Dendrite; Dendritic spine
Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.
A nerve root (Latin: radix nervi) is the initial segment of a nerve leaving the central nervous system. Nerve roots can be classified as: Cranial nerve roots: the initial or proximal segment of one of the twelve pairs of cranial nerves leaving the central nervous system from the brain stem or the highest levels of the spinal cord.
Cranial nerve ganglia contain the cell bodies of cranial nerve neurons. Autonomic ganglia contain the cell bodies of autonomic nerves. In the autonomic nervous system, fibers from the central nervous system to the ganglia are known as preganglionic fibers , while those from the ganglia to the effector organ are called postganglionic fibers .
