Classification, mechanism and surgical treatments for spinal canal cysts

A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies.

Spinal Hydatid cysts

H cyst can involve many systems, mainly the liver and lungs. The liver is the location of 50-70% of Echinococcus granulosus (EG) cysts while 10-30% are in the lungs and 10% in other regions of body. The spinal and cranial regions are rare areas of involvement. Bone involvement is seen in 0.5-4% (8). Bone lesions are most frequently localized at the spine and pelvis. There is no cyst membrane an...

Juxtafacet Spinal Synovial Cysts.

STUDY DESIGN This was a retrospective study. PURPOSE To study the surgical outcome of synovial cysts of the lumbar spine through posterior laminectomy in combination with transpedicular screw fixation.
