Patient 7.
A and B, Diffusion-weighted images (b = 700 s/mm2) at age 18 hours shows reduced diffusion, manifest as high signal intensity (arrows), in the lateral thalami and possibly in the posterior limbs of the internal capsules. No significant reduction in diffusion is seen in the centra semiovale (in B).
C and D, Follow-up diffusion-weighted images (b = 700, s/mm2) at age 7 days at the same levels show reduced diffusion (hyperintensity, arrows) within a much larger area, including the lentiform nuclei and thalami (in C) and along the corticospinal tracts (in D).
E, Axial SE (516/8) image through the basal ganglia shows T1 shortening in the lateral thalami (open arrows) and lentiform nuclei (solid arrows), confirming the injury seen in C.
