FIG 1. MR images showing infarction and dilated blood vessels. A and B, Coronal diffusion-weighted MR imaging (TR, 5000 ms; TE, 120 ms; Td, 85 ms; section thickness, 5 mm) shows multiple cerebellar and brain stem infarcts. C and D, Axial T1-weighted spin-echo MR imaging following gadolinium-DTPA administration (TR, 560 ms; TE, 14 ms; section thickness, 5 mm; interslice gap, 1 mm) demonstrates dilated peripheral middle cerebral artery branches suggestive of fusiform dilatations (arrow).
