Compression of brain [G93.5] / Low back pain [M54.5], Reason for Study: ^Reason: Chiari malformation with back pain and headaches, follow up with CSF flow study History: Chiari malformation and back pain23 years Female (DOB:11/6/1993)Reason: chiChiarilformation with back pain and headaches, follow up with CSF flow study History: Chiari malformation and back painPROVIDER/ATTENDING NAME: DAVID M. FRIM SERVICES ANCILLARY Complete Spine MRIRedemonstration of Chiari I malformation (downward displacement of cerebellar tonsils) are seen, unchanged since prior scan.There is no evidence of syringomyelia.There is normal cervical lordosis. The cranial-cervical junction is normal. 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 cord signal is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal stenosis, cord compression or myelopathy. The conus medullaris terminates at the level of L1-2. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues and musculature are unremarkable.2D Phase Contrast MRA for CSF flowBidBidirectionalF flows across the foramen magnum seen both anterior and posterior aspect of upper cervical cord and cervicomedullary junction. In addition, subtle bidbidirectionalF flow is seen through the foramen Magendie.Comparing to prior scan, there is no significant interval change though this exam is not quantitative.
1. Unchanged Chiari 1 malformation since prior scan.2. No evidence of syringomyelia3. Unchanged bidirectional CSF flow across the foramen magnum both anterior and posterior aspect of upper cervical spine and cervicomedullary junction as well as foramen Magendie.
