Case ReportsLigamentum flavum hematoma in the cervical spine - case report.
A 67-year-old man presented with a rare case of ligamentum flavum hematoma manifesting as progressive tetraplegia following cervical traction therapy. Magnetic resonance imaging of the cervical spine showed a posterior mass that was continuous with the ligamentum flavum at the C3-4 levels. ⋯ We speculate that repeated trivial trauma to the degenerative ligamentum flavum was the main predisposing factor in the present case. Ligamentum flavum hematoma is a rare cause of spinal root or cord compression which typically occurs in the lower thoracic or lumbar spine, but may also appear in the cervical spine.

Case ReportsIntradural retroclival chordoma without bone involvement - case report.
A 63-year-old, previously healthy man presented with a rare large intradural retroclival chordoma without bone involvement. Computed tomography showed that the tumor was completely intradural and did not involve the bone, as confirmed at intraoperative inspection. ⋯ Complete resection is feasible for intradural extraosseous chordoma because of the sharply circumscribed margins and absence of bone involvement. Specialized skull base techniques should be used instead of conventional surgical approaches for intradural skull base chordoma.
