Figure 1. MRI findings over time.

(A) Upper row: FLAIR axial images show progressive white matter lesions without contrast enhancement and distinct cerebral atrophy. Middle row: T1Gd-weighted images show no gadolinium enhancement. Lower row: T2-weighted sagittal images. A prominent radial pattern within T2-weighted axial pictures resembles a previously published patient with glial fibrillary acidic protein meningoencephalitis with a radial pattern of periventricular gadolinium enhancement. (B) T2-weighted sagittal images before daclizumab therapy and during encephalitic illness. T2-weighted axial image shows new focal gliosis at Th 3/4. FLAIR = fluid attenuated inversion recovery; Gd = gadolinium; Th = thoracic vertebra.
