 Brain MRI: The cerebellar tonsils extend up to 8 mm inferior to the foramen magnum and have pointed morphologies. There is narrowing of the cerebrospinal fluid flow across the anterior craniocervical junction and blunted flow of cerebrospinal fluid posteriorly. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a left cerebellar hemisphere developmental venous anomaly. The brain parenchyma otherwise appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. Spine MRI: There is a septated syrinx that extends from the C3 to T6 level, measuring up to 15 mm in width. The conus medullaris terminates at L1 vertebral body level. The spinal cord is freely mobile on prone imaging. There is mild convex right thoracic and convex left lumbar scoliosis. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal or neural foraminal stenosis. The paravertebral soft tissues are unremarkable.
1. Chiari I malformation with associated large cervicothoracic syrinx. 2. Mild thoracolumbar scoliosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
