Synovial cysts arising from the facet joints are rare causes of extradural masses [1, 2]. Almost all cases have been in the lower lumbar spine, but two have been reported in the cervical spine [3, 4]. Presenting symptoms are usually those of radiculopathy. CT and myelographic findings typically are those of a posterolateral extradural mass that may be partially calcified or contain gas [1, 5, 6]. MR findings in six cases have been reported [7]. We present three additional cases of pathologically proved lumbar synovial cysts. The reasons for our report are (1) to describe the previously unreported appearance of these lesions after administration of gadopentetate dimeglumine; (2) to increase the level of awareness of this entity, especially in light of the proliferation of MR as the initial imaging method for evaluating lumbar radiculopathy; and (3) to report the tissue correlation of the MR lesional imaging characteristics.
