Symptomatic Bilateral Cervical Perineural Cyst

Perineural or Tarlov cysts were first described by Tarlov [1] in 1938 during his autopsy studies of the filum terminale [1]. Studies have shown the prevalence of these cysts to vary from 4.6% in some to upto 9% in others [2,3]. Although most of these lesions are asymptomatic, on rare occasions, they may cause local or radicular pain, dysesthesia or paresthesia, paresis and bladder or bowel dysfunction. The ability to diagnose perineural cyst as a cause of neurological dysfunction has been enhanced by CT and MRI.
