Female, 26 years old, with benign intracranial hypertension, Chiari malformation, include cine flow. Brain:Postoperative findings are seen compatible with Chiari decompression including suboccipital craniectomy and resection of the posterior arch of C1. The CSF space at the level of the neo-foramen magnum is well expanded with no evidence of tonsillar or brainstem crowding. Robust biphasic CSF flow is seen both anteriorly and posteriorly through the neo-foramen magnum.Brain parenchymal morphology and signal characteristics are within normal limits. No evidence of edema or mass effect is seen. No acute intracranial hemorrhage or any abnormal extra-axial fluid collections are detected. The ventricles are normal in size and morphology.C-spine:Postoperative findings are seen related to Chiari decompression surgery as above. The osseous structures of the spine are otherwise intact. Straightening of the cervical lordosis is likely positional. Sagittal alignment is otherwise within normal limits. Vertebral body height and morphology are unremarkable. No evidence of marrow replacement or marrow edema is seen.The visualized spinal cord shows normal signal intensity throughout. No epidural abnormalities are suspected.The intervertebral discs are preserved. No significant spinal canal or foraminal stenosis is seen.
1.Findings are seen compatible with Chiari decompression surgery. The CSF space at the level of the neo-foramen magnum is well decompressed with no evidence of brainstem or tonsillar crowding. Adequate CSF flow is seen both anteriorly and posteriorly.2.No specific intracranial abnormalities are identified.3.Apart from surgical changes, no significant abnormalities are seen in the cervical spine.
