T2W hyperintensity of the grey matter throughout the cerebellum and part of the mesencephalon (Figures 1 and 2), with no suppression on FLAIR and no associated contrast enhancement. This T2W hyperintensity was bilaterally symmetrical affecting the caudal cerebellar peduncles, the deep cerebellar nuclei (dentate, interposital and fastigial) (Figure 1) and the rostral and caudal colliculi (Figure 2).
Transverse MRI images of the brain demonstrating the (a) T2-weighted and (b) fluid-attenuated inversion recovery hyperintensity of caudal colliculi (arrowheads)
