“…There is evidence of hypomyelination, with extensive, confluent, progressive, and symmetric signal anomaly in the periventricular and subcortical white matter [ 28 , 66 , 70 , 78 , 79 ]. Apart from the white matter changes, the grey matter changes were described in fucosidosis and are characterized by signal changes in the globi pallidi [ 15 , 28 , 66 , 78 , 79 , 80 ]. This unique-for-fucosidosis feature manifests as marked hypointensity on T2/FLAIR sequences, and hyperintensity on T1 sequences [ 28 , 66 , 76 , 79 ].…”
