Abstract:
The term juxta-facet cyst has been used to characterize two types of periarticular cystic alterations, synovial and ganglion, that can occur in the paraspinal region. Synovial cysts arise from synovial outpouchings through the weakened or destroyed capsular tissue.Ganglion cysts are commonly found about the wrist and hand.But theoretically they can occur at any site in the body where periarticular connective tissue is present. In spinal canal these cysts may cause pressure on adjacent nerve root to produce a variety of neurological symptoms. The clinical features indicated an acute onset of symptoms favoring a diagnosis of disc herniation, so differential diagnosis is important.We have experienced two cases of the intraspinal extradural cysts connected to posterior longitudinal ligament by a sheath, causing nerve root compression. those were managed with excision of the cyst, and no recurrence has been identified during follow up evaluation.
