Spinal cysts

Generally called fluid-filled structure as cysts, which are surrounded by a membrane or wall. Cysts can occur anywhere in the body from various causes. In the spine, there are two main types of cysts, perineural cysts and synovial cysts. Cysts can gain in importance, as they become larger and thereby press on surrounding structures. In the spinal canal, are the nerve roots which may be harassed by a cyst. Thus, the typical symptoms of the so-called root compression syndrome or spinal claudication occur (disease of the spinal canal narrowing). Cysts are best imaged with MRI, especially on T2-weighted spin-echo sequences, because in this presentation liquid is white and is best distinguished from the surroundings.
