Brain MRI scans of a 20-year-old male patient affected by MPS II (attenuated form). Axial FLAIR image a shows periventricular and subcortical (arrows) white matter lesions (lesion load = 1.8%). Axial T2-weighted image b shows dilated perivascular spaces (score 3) prominently seen in the thalami and basal ganglia (arrow) and enlargement of subarachnoid spaces. Midsagittal T2-weighted image c shows dilated perivascular spaces within the corpus callosum (arrowhead), and effacement of CSF (arrow) and spinal stenosis at C1–C2 (score 1)
