Abstract
Tarlov's cyst or perineurial cyst is disease on portion of the posterior nerve root in lumbo-sacral region. The lack of knowledge of physicians around the world about Tarlov's cyst as to their nature, significance and treatment also with differential diagnostics to radiculopathy in legs. With review of literature discuss about definition, etiopathogenesis, diagnostic investigation and treatment clinic and/or surgery. The pathogenesis Tarlov's cyst remains unclear; several cases have history of the trauma, old hemorrhage, congenital and iatrogenic. Cysts provoke low back pain, sacral radiculopathy, dyspareunia, urinary incontence. The magnetic resonance imaging is now the gold standard to diagnose cysts. The treatment is clinic or surgery depending neurologics finding and neuroimage.

RESUMEN
El quiste de Tarlov o quiste perineural son lesiones de las raíces nerviosas localizadas a nivel de la región sacra y de etiología incierta. La mayoría de estos quistes permanecen asintomáticos y carecen de relevancia clínica. Los quistes sintomáticos son infrecuentes y los síntomas más habituales son el dolor y las radiculopatías. Nosotros presentamos el caso de una mujer de 53 años con un quiste de Tarlov sintomático ( síndrome de frecuencia y urgencia miccional) que tras el tratamiento quirúrgico presenta una mejoría clínica importante.
Palabras clave: Quiste Tarlov. Sintomático. Disfunción. Vesical.

Abstract
Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.

Spinal perineurial and meningeal cysts.

Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fails to reveal an adequate cause for the patient's symptoms and signs referable to the caudal nerve roots, then about a millilitre of Pantopaque should be left in the canal for delayed myelography which may later reveal a sacral perineurial cyst or, occasionally, a meningeal cyst. Meningeal diverticula occur proximal to the posterior root ganglia and usually fill on initial myelography. They are in free communication with the subarachnoid space and are rarely in my experience responsible for clinical symptoms. Meningeal diverticula and meningeal cysts appear to represent a continuum. Pantopaque left in the subarachnoid space may convert a meningeal diverticulum into an expanding symptomatic meningeal cyst, as in the case described. Many cases described as perineurial cysts represent abnormally long arachnoidal prolongations over nerve roots or meningeal diverticula. In general, neither of the latter is of pathological significance. Perineurial, like meningeal cysts and diverticula, may be asymptomatic. They should be operated upon only if they produce progressive or disabling symptoms or signs clearly attributable to them. When myelography must be done, and this should be done only as a preliminary to a probable necessary operation, then patient effort should be made to remove the Pantopaque
