 Multifocal bihemispheric and supra and infratentorial high signal intensity lesions on FLAIR images involving periventricular, subcortical, corpus callosum, midbrain, pons, medulla and bilateral cerebellar hemispheres which are consistent with the diagnosis of multiple sclerosis are seen, unchanged in terms of their extent, configuration and number since prior scan. There is prominence of the ventricles and the sulci suggestive of volume loss, again unchanged. There is no restricted diffusion. There are few foci in the periventricular white matter of high signal in the diffusion and in the ADC sequence, representing T2 shine through. There are no susceptibility abnormalities.
No significant changes of multifocal white matter lesions on FLAIR images since the previous study.
