RT Journal Article SR Electronic T1 Synovial cyst of the high cervical spine causing myelopathy. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 981 OP 982 VO 13 IS 3 A1 G Quaghebeur A1 M Jeffree YR 1992 UL http://www.ajnr.org/content/13/3/981.abstract AB The authors describe the myelographic and postmyelographic CT findings of an extradural mass with cord compression in an 82-year-old woman. Synovial cysts generally occur posterolaterally and are associated with degenerative facet joints; an unusual site together with facet joint disease should alert the observer to the possibility of a synovial cyst.
