Tarlov cysts are fluid-filled nerve root cysts found most commonly at the sacral level of the spine – the vertebrae at the base of the spine. These cysts typically occur along the posterior nerve roots. Cysts can be valved or nonvalved. The main feature that distinguishes Tarlov cysts from other spinal lesions is the presence of spinal nerve root fibers within the cyst wall, or in the cyst cavity itself.

Due to the close proximity to the lower pelvic region, patients may be misdiagnosed with herniated lumbar discs, arachnoiditis, and in females, gynecological conditions. An accurate diagnosis may be further complicated if the patient has another condition that affects the same region.
