Diagnosis: Compression of brain Headache CervicalgiaClinical question: Chiari malformation , yearly follow up , please do with CSF flow studySigns and Symptoms: headaches, neck pain MRI brain:The CSF spaces are appropriate for the patient's stated age with no midline shift. The patient is status post suboccipital craniotomy for Chiari decompression.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRI cervical spine:The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. A small syrinx measuring up to 1.5 mm is present at the C5 level approximately 1 cm in length.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. There is a small central disc protrusion at this level.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.Lumbar spine:Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is a mild disc bulge present at this level.At L4-5 there is no significant compromise to spinal canal or neural foramina.At L3-4 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.Status post Chiari I decompression. There is no obstruction at the level of the foramen magnum.2.Small syrinx is present in the cervical spinal cord at the C5 vertebral body level.3.There are minor degenerative changes present in the cervical and lumbar spine.
