Multiple sclerosis

The axial FLAIR image reveals numerous punctate, predominantly discrete, small hyperintense foci in the supraventricular white matter. Cord lesions and characteristic callosal lesions on the sagittal FLAIR image confirm the diagnosis of multiple sclerosis, with the caveat that the lesion load is very high in this patient. A post-contrast T1-weighted axial scan reveals lesions without enhancement (‘black hole’), punctate enhancement, and ring enhancement.
