Evaluate Syrinx, history of Chiari malformation. Motion artifacts degraded image quality.About 20.7mm of caudal cerebellar tonsilar herniation was seen which is compatible with Chiari malformation.Syrinx is seen from the level of C23 to T78.There is normal thoracic kyphosis and lumbar lordosis. The spine alignment appear to be 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 narrowing, cord compression, or myelopathy. The conus medullaris terminates at the T12-L1 level. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues are unremarkable.
1. Chiari malformation with about 20.7mm tonsilar herniation.2. Syrinx from the level of C23 disc space to T78 vertebral level.
