Abstract
Diaschisis is the inhibition of function produced by focal disturbances in a portion of the brain at a distance from original site of injury. Many studies using brain SPECT (single-photon emission computed tomography) have demonstrated crossed cerebellar diaschisis (CCD) in patients with cerebral cortical infarct. We report a case of cerebrovascular accident involving the left middle cerebral artery territory. PET/CT performed one month after stroke showed hypometabolism in the left cerebral hemisphere with hypometabolism of the contralateral cerebellum. The finding of diminished glucose metabolism in the contralateral cerebellum represents CCD.
