Male, 58 years old, with history of multiple sclerosis, assess for interval change. Multiple small T2 hyperintense lesions are evident involving the periventricular and juxtacortical white matter of both cerebral hemispheres. The brainstem and cerebellum are spared.On comparison with the prior examination, two new lesions are seen, one in the left frontal operculum (image 54 series 501), and one in the superficial right middle frontal gyrus (image 69 series 501). Another lesion in the right occipital periventricular white matter (image 117 series 401) is larger. The remaining lesions are unchanged. The lesions demonstrate mild to moderate T1 hypointensity.No areas of significant parenchymal edema or mass effect are detected. No abnormal extra-axial collections are seen. The sulci and ventricles are very mildly prominent compatible with underlying volume loss.
Several scattered lesions are seen compatible with multiple sclerosis in the bilateral cerebral hemispheres. On comparison with the prior examination, two lesions are new and one is larger.
