Female, 28 years old, with myoclonic jerking in the right upper extremity, history of motor vehicle accident in 2011, history of melanoma. Rule out MS or other lesion. Brain:The cerebral and cerebellar hemispheres and brainstem show normal signal intensity and morphology. No restricted diffusion is seen. No pathologic enhancement is detected.

There is no evidence of intracranial hemorrhage or abnormal extra-axial fluid. The ventricular system is normal in caliber and morphology. Signal intensity of the bone marrow is unremarkable. No significant abnormalities of the paranasal sinuses are detected.Cervical spine:Alignment is anatomic. Vertebral body height and morphology are within normal limits. No pathologic marrow replacement or enhancement is seen.The visualized spinal cord demonstrates normal signal intensity and morphology. No focal lesions are seen. No pathologic intramedullary or leptomeningeal enhancement is detected. No epidural lesions are seen.There may be a very small central disc protrusion at C6-7. Elsewhere the intervertebral discs are preserved. No significant spinal canal or foraminal stenosis is observed.
