Temporal evolution of right-sided inferior olive hypersignal in a patient with symptomatic oculopalatal tremor. The patient presented a right-sided pontine tegmental lesion in June 2014 seen on the diffusion MRI scan (A), and the medulla showed no abnormal hypersignal on FLAIR MRI (B). Subsequently, right inferior olive hypersignal was observed 6 months later (C), with increasing signal 1 year later (D) and right inferior olive hypertrophy was observed 2 years later (E).
