Brain magnetic resonance imaging (MRI) showed T1-weighted isointense and T2 and fluid-attenuated inversion recovery hyperintense signal in bilateral cerebellar hemispheres including vermis, with minimal diffusion restriction and nongadolinium enhancement [Figure 1].
Repeat magnetic resonance imaging brain axial images after 3 months showing partial resolution of the previous hyperintense signals in bilateral cerebellar hemispheres: (a) T1-weighted image, (b) T2-weighted image, (c) fluid-attenuated inversion recovery image
