Worsening clinical features in a patient with right middle cerebral artery territory stroke

Abstract

We describe a case with acute ischemic stroke in the right MCA territory. He developed secondary deterioration for which no obvious cause could be found. He underwent FDG-PET for evaluating carotid plaque inflammation as part of a research study, which revealed considerable hypometabolism in the left cerebellar hemisphere-responsible for the neurological deterioration. This phenomenon is often called ‘crossed cerebellar diaschisis. Various imaging findings are presented.
