FIG 1. Images obtained at initial examination, performed when the patient was 10 months old.

A, T2-weighted image reveals hyperintense changes in the deep white matter and atrophy.

B, A b = 1000 mm²/s (heavily diffusion-weighted) image from an echo-planar trace sequence reveals hyperintense changes similar to those of cytotoxic edema.

C, Corresponding ADC map reveals a low signal intensity and low ADC value (0.55 x 10^-3 mm²/s) in the deep white matter compared with the peripheral regions of the parenchyma, including peripheral white matter and the cortex (0.95 x 10^-3 mm²/s).
