Reason: Chiari 1 malformation History: headaches MRI brain:The CSF spaces are appropriate for the patient's stated age with no midline shift. Metal artifact from the patient's oral cavity - presumably from dental hardware - partially degrades imaging and obscures visualization of the orbits. The DWI and SWI images are significantly degraded.No abnormal enhancing 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 demonstrate partial opacification of the visualized portions of the sphenoid sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.There is no evidence for Chiari one malformation. The cerebellar tonsils are low lying extending approximately 2 to 3 mm below the level of foramen magnumMRI cervical spine:The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. No abnormal enhancing lesions are identified in the cervical spine.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:The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. No abnormal enhancing lesions are identified in the thoracic spine.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. No abnormal enhancing lesions are identified in the lumbar spine.At L5-S1 there is no significant compromise to spinal canal or neural foramina.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.The cerebellar tonsils are low lying. There is no convincing evidence for Chiari I malformation.2.There is no evidence for ventriculomegaly of syrinx.3.There is no compromise to the cervical, thoracic or lumbar spinal canal or neural foramina.4.Exam is somewhat degrade by metal artifact related to the patient's dentition.
