![T1 and T2 weighted MRI images (left) showing loss of neuronal tissue in the distribution of the RMCA in the right cerebral hemisphere with focal dilatation of the right lateral ventricle. MRA showed absence of blood flow in RMCA and RACA (not shown). Marked FDG (metabolic) and ([15O] H2O) (perfusion) deficits on PET imaging (right) are seen throughout the right hemisphere (arrowheads) with near total neuronal loss (infarction). Deficits are greatest in the cerebral cortex of the RMCA distribution. Left cerebral cortex shows focal deficits best seen on FDG-PET (arrowhead).](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/93/1/10.1182_blood.v93.1.71/5/blod401pow04z.jpeg?Expires=1722260277&Signature=MlzUTuZv6IgeNlPAqj50tvnoAb-7ICaQNrQAOWvLFCyolonwIsMiXxMYnm9p83IL7VnNeYpRs0t1nEHs5O6BMr5a52I~468XSCkZXbpfPd4RMV3MdL1Ee-wxyE7m6glupPrLte-HdZqSopav3J5PMyPVJUZy3nCwW8FMgHkcHNEyU~9dwmvSYrlhXDWQ3mAb79i0PoEUvkodic1OSvuwtSQPudpoV2v8Jx~-XmBLBKdfgkIpq3F3qWO0F1qeN3jcLXgVSiTabhpdg38Zm6w4pxz9HXz3buPfuE5f0WTp3rM13dBDLGBuaoSlNvN0ivFLtaB9XsAv03AGkQS63ay3VQ__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
