Tarlov quistes son la columna vertebral raíz nerviosa lesiones lleno de líquido cefalorraquídeo, que se encuentra más a menudo en los niveles inferiores de la columna vertebral. Tarlov quistes puede ser asintomática o causar potencialmente una grave enfermedad neurológica. Los estudios preliminares sugieren que alrededor del 1% del ciático o ciático-como síntomas pueden ser causados por quistes Tarlov. Otros nombres para Tarlov y los quistes son la columna vertebral o perineural perineurial quiste, quiste meníngea, y quiste aracnoideo. Leer más ... Una propensión Tarlov para el desarrollo de los quistes puede ser pasado a través de la madre o el padre. Tarlov quistes se encuentran la mayoría de las veces cuando el lumbar y sacra niveles de la columna vertebral son escaneados por resonancia magnética para otras condiciones. A pesar de la actualidad, estos quistes por lo general no causa síntomas evidentes. Sin embargo, Tarlov quistes a menudo han sido despedidos por los radiólogos como "incidental", aunque los pacientes que tienen síntomas podrían ser causados por un quiste Tarlov. IIN tales casos, Tarlov quiste no puede ser eliminada por radiología. Los síntomas pueden ser iniciadas por los traumas ocasionados por un evento como una caída, accidente de auto o levantar objetos pesados. El inicio puede ser gradual o repentino, leve o grave, y la progresión y, en última instancia la gravedad de los síntomas difieren ampliamente. Tarlov quistes en fase de la enfermedad suele causar dolor disfunción neurológica en el camino de la raíz nerviosa afectada. Tarlov quistes difieren en su estructura. Un quiste puede incorporar elementos o los nervios se libre de ellos. Un quiste puede ser válvula o no válvula. Una válvula tiene un quiste en la estructura de su cuello que hace que sea más fácil para el líquido cefalorraquídeo para entrar en el quiste que salir de casa. En una válvula no quiste, líquido cefalorraquídeo fluye libremente entre el quiste y el tubo dural. Tarlov quistes suelen ser posterior en las raíces; anterior quistes son poco frecuentes. Tarlov múltiples quistes no son poco frecuentes. Aunque un gran quiste puede causar síntomas de presión sobre una estructura adyacente, los síntomas pueden ser causados por las fuerzas hidrostática de la columna vertebral de fluidos en el interior del quiste ejercer presión sobre los nervios en el quiste o quiste wall.1 las pulsaciones del líquido cefalorraquídeo hace que el quiste a ampliar, potencialmente elementos de estiramiento del nervio y causando el aumento o symptoms.2 Por lo tanto, los quistes, incluso más pequeño que un centímetro puede ser muy sintomático. Los síntomas más comunes son dolor en la parte baja de la espalda, las nalgas y las piernas, pero los muslos, las piernas y los pies puede ser o no ser involved.3 Los síntomas pueden ser caras opuestas. Tarlov quistes también pueden causar dolor y trastornos en los órganos de eliminación y la reproducción, hipoestesia, parestesias, y la claudicación neurógena (dolor en el muslo de la falta de suministro de sangre) .4 Las posturas de sentado, de pie, caminar, y son típicamente de flexión dolorosa , Reclinables y plano sobre el lado suele ser la única postura que ofrece socorro. Una persona que tiene un quiste y Tarlov cualquier síntoma Tarlov quiste necesidades de evaluación por un especialista que tiene la experiencia para determinar si los síntomas son Tarlov de un quiste o de otra condición de la columna vertebral. Sin embargo, algunos especialistas están familiarizados con el pleno alcance de Tarlov quiste sintomatología y los últimos avances en el tratamiento. Una variedad de técnicas quirúrgicas han sido empleados para Tarlov quistes, pero es extremadamente raro que un cirujano han operado en un número importante de los quistes Tarlov con beneficio para la mayoría de los pacientes. Un procedimiento mínimamente invasivo de los quistes Tarlov implica la aspiración del quiste seguido por la inyección de pegamento de fibrina ( "AFGI"). Este procedimiento ha sido eficaz para algunos de sus miembros. Los principales centros para el tratamiento de los quistes Tarlov (Universidad Johns Hopkins, Baltimore, y la Universidad Louis Pasteur de Estrasburgo) sobre AFGI tratar adecuadamente válvula quistes antes de recurrir a la cirugía. Para RM de Tarlov quistes, de intervención neuroradiologist Dr MR Patel recomienda la exploración axialmente a través del quiste y, en post-operatorio, para obtener pre-y post-gadolinio imágenes axiales. Neurología India En la medida en que la enfermedad es rara, el número de Tarlov tratan los quistes en cualquier parte del mundo es pequeño. Por lo tanto, la cooperación internacional será fundamental para la evaluación y el perfeccionamiento de nuevos tratamientos prometedores. Subsidios de investigación otorgados por el gobierno nacional son generalmente asignados a las enfermedades más comunes. En este momento, estamos aceptando donaciones de los pacientes y de otros benefactores y filántropos, a un fondo que nos permita invitar y facilitar las reuniones con respecto a la posible colaboración en Tarlov quistes entre la Universidad Louis Pasteur de Estrasburgo, Francia. y la top-rated American hospital Johns Hopkins, de Baltimore, Maryland, y los primeros del mundo en Tarlov quiste expertos que están afiliados a estas instituciones.

Introduccion
Introduction
Tarlov cysts are spinal nerve root lesions filled with spinal fluid, found most often at the lower levels of the spine. Tarlov cysts can be asymptomatic or cause a potentially serious neurological disease. Preliminary studies suggest that about 1% of sciatic or sciatic-like symptoms may be caused by Tarlov cysts. Other names for Tarlov and related spinal cysts are perineural or perineurial cyst, meningeal cyst, and arachnoid cyst.

A propensity for developing Tarlov cysts may be passed through the mother or father. Tarlov cysts are most often found when the lumbar and sacral levels of the spine are scanned by MRI for other conditions.
Even though present, these cysts usually cause no apparent symptoms. However, Tarlov cysts have frequently been dismissed by radiologists as "incidental" even though the patients have symptoms that could be caused by a Tarlov cyst. Iin such cases, Tarlov cyst cannot be eliminated by radiology.
Symptoms may be initiated by trauma incurred in an event such as a fall, auto accident or heavy lifting. The onset may be gradual or sudden, mild or severe, and the progression and ultimate severity of symptoms differ widely. Tarlov cysts in the disease stage usually cause pain neurological dysfunction in the path of the affected nerve root.
Tarlov cysts differ in structure. A cyst might incorporate nerve elements or be free of them. A cyst can be valved or non-valved. A valved cyst has a structure in its neck that makes it easier for spinal fluid to enter the cyst than to leave. In a non-valved cyst, spinal fluid flows freely between the cyst and the dural tube.
Tarlov cysts are typically on posterior roots; anterior cysts are rare. Multiple Tarlov cysts are not uncommon. Although a large cyst can cause symptoms by pressing on an adjacent structure, symptoms may also be caused by hydrostatic forces of the spinal fluid inside the cyst exerting pressure on nerves in the cyst or cyst wall.1 The pulsations of spinal fluid causes the cyst to expand, potentially stretching nerve elements and causing or increasing symptoms.2 Therefore, cysts even smaller than one centimeter can be highly symptomatic.
The most common symptoms are pain in the low back, buttocks and legs, but the thighs, legs and feet may or may not be involved.3 Symptoms can be opposite-sided. Tarlov cysts can also cause pain and disorders in the organs of elimination and reproduction, hypoesthesia, paresthesias, and neurogenic claudication (pain in the thigh from lack of blood supply).4 The postures of sitting, standing, walking, and bending are typically painful, and reclining flat on the side is usually the only posture that offers relief.
A person who has a Tarlov cyst and any Tarlov cyst symptom needs evaluation by a specialist who has the expertise to determine if the symptoms are from a Tarlov cyst or another spine condition. However, few specialists are familiar with the full scope of Tarlov cyst symptomology and recent advances in treatment.
A variety of surgical techniques have been employed for Tarlov cysts, but it is extremely rare for a surgeon to have operated on a substantial number of Tarlov cysts with benefit to most patients.
A minimally invasive procedure for Tarlov cysts involves aspiration of the cyst followed by injection of fibrin glue ("AFGI"). This procedure has been effective for some members. The leading centers for treatment of Tarlov cysts (Johns Hopkins University, Baltimore, and University Louis Pasteur, Strasbourg) try AFGI on suitably valved cysts before resorting to surgery.
For MRI of Tarlov cysts, interventional neuroradiologist Dr. M. R. Patel recommends scanning axially through the cyst and, post-operatively, to obtain pre- and post-Gadolinium axial images.
Neurology India
Inasmuch as the disease is rare, the number of Tarlov cysts treated in any part of the world is small. Therefore, international cooperation will be crucial to the evaluation and refinement of promising new treatments. Research grants from national government are typically allocated to the more common diseases. At this time, we are accepting donations from patients and other benefactors and philanthropists, to a fund that will enable us to invite and facilitate meetings with regard to potential collaboration on Tarlov cysts between the University Louis Pasteur, Strasbourg, France. and the top-rated American hospital, Johns Hopkins, of Baltimore, Maryland, and the world's top Tarlov cyst experts who are affiliated with these institutions.
