From the case: Hypertrophic olivary degeneration
There is a linear T2-hyperintensity focus with a T2-hypointense rim at the left pons, tends to lateral wall of 4th ventricle through left superior cerebellar peduncle. Same focus localized at right nucleus caudatus. Note enlarged hyperintense both inferior olivary nuclei. Also there are many confluent foci of T2 hyperintensity within anterior and posterior horns, both corona radiata, reflecting small vessel ischaemia. Enlarged perivascular spaces in basal ganglia D=S.
