(a) Axial two-dimensional fluid-attenuated inversion-recovery image shows a new demyelinating lesion in the right superior cerebellar peduncle (arrow). (b) Follow-up axial two-dimensional fluid-attenuated inversion-recovery image 3 months later demonstrated new hyperintensity and subtle enlargement of the left inferior olivary nucleus (arrow).

MRI of the head showed a new T2/fluid-attenuated inversion-recovery (FLAIR) hyperintense lesion in the right superior cerebellar peduncle (SCP) (Figure 1a). Follow-up MRI performed 3 months later, however, revealed a new T2/FLAIR hyperintense expansile lesion in the left inferior medullary olive and persistence of the initial right SCP T2/FLAIR hyperintense lesion (Figure 1b).
