Early Development of Syringomyelia after Spinal Cord Injury: Case Report and Review of the Literature.

We report a case of post-traumatic syringomyelia (PTS), which developed 2 months after spinal cord injury (SCI). A 20-year-old man who was involved in a motorcycle accident sustained a complete SCI resulting from a burst fracture of the T5 vertebral body. He underwent posterior fixation with decompression at another hospital 2 days after the injury.

[An Extracranial Aneurysm in the Distal Posterior Inferior Cerebellar Artery Located at the Tonsillomedullary Segment:Case Report and Review of the Literature].

We report a rare case of subarachnoid hemorrhage(SAH)due to ruptured extracranial aneurysm originating at the caudal loop of the left posterior inferior cerebellar artery(PICA). A 50-year-old woman presented with severe headache and mild consciousness disturbance. Computed tomography(CT)revealed SAH and intraventricular hemorrhage.

Retro-odontoid synovial cyst resected via an anterolateral approach without fusion.

Purpose: Retro-odontoid synovial cysts are rare and attributable to degenerative changes in the atlantoaxial joints. An anterolateral approach facilitates access to lesions located anterior to the craniocervical junction without harming the atlantoaxial joints, and can also treat small lesions in the ventral mid-portion of the craniocervical junction without compression of spinal cord.

Methods: We present herein the case of a 70-year-old man with a retro-odontoid synovial cyst.
