Traumatic extradural spinal cysts: a case report and review of the literature.
Extradural spinal cysts, although unusual, are well-documented entities. The majority are of congenital origin while only a few with a clear cut traumatic pathogenesis are reported. We present a case of a traumatic extradural spinal cyst which presented as a progressive radiculopathy following a penetrating injury. We also review the literature concerning traumatic extradural spinal cysts and show that they can occur following a wide variety of spinal trauma. The trauma must involve sufficient force to cause a dural rent and iatrogenic causes are included. The differences and similarities between traumatic and congenital cysts are shown, and treatment is discussed. The prognosis following surgical resection is shown to be excellent.
