Lumbar intraspinal synovial cysts are included in the difference diagnosis of lumbar radiculopathy. Developing imaging modalities has result in increased reporting about these lesions. However, the case of bilateral new lumbar intraspinal synovial cysts after laminectomy has been rarely reported. We report of a rare case with bilateral lumbar intraspinal synovial cysts after laminectomy, requiring surgical excision.

Spinal cord compressing syndrome due to synovial cyst (SC) of the thoracolumbar spine is a rare clinical condition. In this report we aim to heighten awareness of the thoracolumbar facet synovial cyst as a possible cause of thoracic myelopathy. The SC was removed thoroughly by laminectomy. The patient had an excellent recovery. The etiological and therapeutic aspects are discussed.

Synovial cyst on prevertebral space of C1-2 joint is rare but may be associated hemorrhagic event. We describe a case of a 72-year-old woman who presented with sudden severe headache in her left occipital area with dyspnea. She had rheumatoid arthritis for 14-years. Large hemorrhagic cystic mass was seen around prevertebral space of the atlantoaxial joint on the left side on cervical MRI (magnetic resonance image) and it obstructed the nasopharyngeal cavity. Aspiration of the cystic lesion was performed via transoral approach, followed by posterior occipito-cervical fusion. The specimen was xanthochromic, suggesting old hemorrhage. The patient was tolerable on her postoperative course and showed good respiration and relieved headache. We suggest that repeated microtrauma due to atalantoaxial subluxation associated with rheumatoid arthritis as a main cause of hemorrhagic event on the cyst.
