Somnolence [R40.0], Reason for Study: ^Reason: anatomic abnormalities? Chiari? History: LOC concerning for seizure CSF flow study and L-spine prone scan were not performed per the request of ordering service.Extensive syringomyelia starting C2 level to T9 level is seen.The syrinx cavity shows septation in whole length.There is no evidence of associated vertebral body abnormality. There is normal cervical lordosis. There is normal thoracic kyphosis and lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal stenosis, cord compression. The conus medullaris terminates at the level of T12-L1. There is no evidence of tethered cord or spinal dysraphism. The filum terminale is normal in size and signal intensity. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues and musculature are unremarkable.
1. Chiari I malformation with extensive syringomyelia from C2 to T9 level as described above.2. Otherwise no remarkable finding.
