Magnetic resonance imaging of the brain. The axial fluid-attenuated inversion-recovery (FLAIR) image shows multiple hyperintensity lesions in the left occipital white matter and in the left internal capsule (a). The post-contrast T1-weighted image shows multiple rounded lesions with peripheral capsular enhancement in the corresponding area (b). Almost four weeks later, multiple hyperintensity lesions in the left occipital white matter and the left internal capsule (c) as well as multiple enhanced lesions (d) are diminished in size and intensity.
