46 years, Male, left arm weakness, rule out structural lesion. Brain: Brain parenchyma is within normal limits for age. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses are clear aside from small bilateral maxillary mucus retention cysts. Mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits. Cervical Spine: Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained aside from some straightening which may be in part positional. Bone marrow signal is within normal limits. The cervical spinal cord has normal signal characteristics and overall morphology.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: Mild right-sided neural foraminal stenosis related to mild disc bulge, uncovertebral hypertrophy and mild facet arthropathy. No significant compromise to the spinal canal or left neural foramen.C4-5: Small right paracentral disc protrusion. No significant compromise to the spinal canal or neural foramina.C5-6: Minimal disc bulge. No significant compromise to the spinal canal or neural foramina.C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.Scattered small bilateral perineural cysts. The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1. Brain parenchyma appears within normal limits.2. Mild degenerative changes in the cervical spine without significant spinal canal stenosis at any level. No cord signal abnormality. No significant left neural foraminal narrowing at any level.
