FIG 4. A 26-year-old man with sCJD.
A, Axial DWI shows extensive, asymmetric, right-greater-than-left neocortical involvement and abnormal hyperintensity of right caudate nucleus, putamen, and thalamus (arrowheads). Left caudate nucleus may be mildly hyperintense, but left putamen and thalamus are not definitely abnormal.
B, More superior axial DWI shows involvement of posterior frontal (top arrowhead) and anterior parietal (bottom arrowhead) cortex, with sparing of cortex on edges of the central sulcus (arrow).
