Isadore Tarlov
Isadore Max Tarlov (May 16, 1905 – June 4, 1977) was an American neurosurgeon, academic and researcher. He was the first doctor to provide a methodical description of perineurial cysts of the spinal region, which are now known as Tarlov cysts. Biography Tarlov was born in Norwalk, Connecticut, to Russian Jewish immigrant parents. He graduated from Clark University and earned his medical degree from Johns Hopkins University in 1930. During World War II, Tarlov researched the use of blood plasma clotting agent as an adhesive to repair nerve cells. 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 result of meningeal diverticula and long arachnoid prolongations. It wasn't until 10 years later that he discovered their significance, and that these cysts can appear symptomatic in patients. An important disti ...

Tarlov Cyst
Tarlov cysts, are type II innervated meningeal cysts, cerebrospinal-fluid-filled (CSF) sacs most frequently located in the spinal canal of the sacral region of the spinal cord ( S1– S5) and much less often in the cervical, thoracic or lumbar spine. They can be distinguished from other meningeal cysts by their nerve-fiber-filled walls. Tarlov cysts are defined as cysts formed within the nerve-root sheath at the dorsal root ganglion. The etiology of these cysts is not well understood; some current theories explaining this phenomenon have not yet been tested or challenged but include increased pressure in CSF, filling of congenital cysts with one-way valves, and/or inflammation in response to trauma and disease. They are named for American neurosurgeon Isadore Tarlov, who described them in 1938. Tarlov cysts are relatively uncommon when compared to other neurological cysts. Initially, Isadore Tarlov believed them to be asymptomatic, however as his research progressed, Tarlov f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Filum Terminale
The filum terminale ('terminal thread') is a delicate strand of fibrous tissue, about 20 cm in length, extending inferiorly from the apex of the conus medullaris to attach onto the coccyx. The filum terminale acts to anchor the spinal cord and spinal meninges inferiorly. The upper portion of the filum terminale is formed by spinal pia mater within a dilated dural sac, while the lower portion is formed by both pia and dura mater (with the outer dural layer closely adhering to the inner pial component). Anatomy The proximal/superior partthe filum terminale internum or pial part of terminal filummeasures 15 cm in length and extends as far as the inferior border of the second sacral vertebra (S2) (the inferior limit sacral canal). It is composed of the vestiges of neural tissue, connective tissue, and neuroglial tissue lined by pia mater. It is contained within a tubular sheath of the dura mater and is surrounded by the nerves of the cauda equina (from which it can ...
