Preferred Label : Tarlov cyst;
ICD-11 definition : Meningeal dilations of the posterior spinal nerve root sheath that most often affect
sacral roots and can cause a progressive painful radiculopathy. Tarlov cysts are most
commonly diagnosed by lumbosacral magnetic resonance imaging and can often be demonstrated
by computerized tomography myelography to communicate with the spinal subarachnoid
space. The cyst can enlarge via a net inflow of cerebrospinal fluid, eventually causing
symptoms by distorting, compressing, or stretching adjacent nerve roots.;
