Female patient aged 36 years, known case of multiple sclerosis on follow up, presented by clinical signs of activity. A, B Axial pre and post-contrast T1WI respectively showed no definite lesions. C Axial pre-contrast FLAIR showed few foci of high signal intensity at periventricular white matter. D Axial post-contrast FLAIR showed nodular enhancement of MS plaques (arrows) and gyriform enhancement at left parietal lobe was better demonstrated than in post-contrast T1W image
