 BRAIN: There postoperative findings related to suboccipital craniectomy for Chiari I malformation. There is bilateral inferior cerebellar tenting towards the overlying dura. There is intact biphasic flow across the neo-foramen magnum, although there appears to be mild flow turbulence posteriorly along the inferior cerebellum. There is unchanged flexion of the brainstem configuration. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles are unchanged in size and configuration. The major cerebral flow voids appear to be intact. The clivus is hypoplastic and associated with platybasia. SPINE: The holocord syringohydromyelia has decreased in caliber, measuring up to 3 x 7 mm in cross section, previously 7 x 12 mm. There is more pronounced thoracolumbar scoliosis and straightening of the vertebral column in the sagittal plane. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis.
1. Postoperative findings related to Chiari decompression with evidence of adhesion formation between the inferior cerebellum and overlying dura in the surgical bed and persistent craniocervical junction malformation manifesting with platybasia.2. Interval decrease in caliber of the holocord syringohydromyelia.3. More pronounced thoracolumbar scoliosis, perhaps attributable to the absence of a brace during the scan.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
