Female, 31 years old, with demyelinating disease and paresthesias. Assess white matter abnormalities. Redemonstrated are several (at least 5) very small foci of T2 hyperintensity scattered throughout the periventricular and subcortical white matter. Accounting for differences in technique, including 3T versus 1.5 T imaging, there has been no significant interval change in the size or number of these lesions. As on the prior examination, none of these lesions demonstrates pathologic enhancement. No evidence of any new intracranial lesion is seen. There are no findings to suggest parenchymal edema or mass effect. No intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles are normal in size and morphology.
No significant interval change in the size or number of several scattered very small white matter lesions.
