11-year-old male with syrinx cervical and thoracic spine, yearly evaluation, history of Chiari decompression. Evaluate for changes to syrinx. Cervical spine: Again seen are stable postsurgical changes related to Chiari decompression with intact biphasic CSF flow through the foramen magnum anterior and posterior to the spinal cord. The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology.At C2-3 there is no significant compromise to the spinal canal or neural foramina.At C3-4 there is no significant compromise to the spinal canal or neural foramina.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.Thoracic Spine: Syrinx in the upper thoracic spinal cord is unchanged measuring up to 5 mm in maximal width. The thoracic vertebral bodies are appropriate in overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no evidence of spinal canal or neural foraminal stenosis.
1. Stable postsurgical changes of Chiari decompression with appropriate CSF flow. 2. Syrinx in the upper thoracic spinal cord is unchanged.
