title: Case report: intraspinal synovial cyst containing gas.
abstract: With MRI, an intraspinal synovial cyst appears as a hypointense, rounded, intraspinal lesion bearing similar signal characteristics to cerebrospinal fluid containing a signal void within it; this can be confused with calcium or hemosiderin within the cyst. In such cases, CT imaging can lead to a diagnosis.
