32-year-old with history of multiple sclerosis presenting with dysmetria on left hand with finger to nose, veers to left while walking No restricted diffusion to indicate acute ischemia. There are multiple foci of increased T2 signal in the periventricular and subcortical white matter as well as the posterior limb of the internal capsule bilaterally, left cerebral peduncle and the left corpus medullare cerebelli. These lesions are not associated with decreased signal on the T1 sequences. No abnormal enhancement is noted on the postcontrast sequences.There is no evidence of intracranial hemorrhage or mass. The ventricles and basal cisterns are normal in size and configuration. The expected intracranial vascular flow voids are present. The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.
Scattered foci of white matter increased T2 signal compatible with the patient's stated history of multiple sclerosis. There is no associated decreased T1 signal or enhancement within these lesions. A lesion within the left corpus medullare cerebelli may correlate with the patient's current symptoms, but comparison with prior imaging would be helpful to assess for interval change.
