title: The value of MRI in the study of spinal extradural arachnoid cysts.
abstract: Two cases of extradural arachnoid cyst in the spinal canal were diagnosed by magnetic resonance imaging (MRI). MRI correctly characterized the extradural location of the cysts as well as the cyst contents as CSF, thus establishing the diagnosis. MRI may be of predictive value in the postoperative prognosis.
