This reports positron emission tomography and [ 18 F]fluorodeoxyglucose (PET‐FDG) in a 69‐year‐old woman who underwent resection of the left cerebellar hemisphere for an acoustic neurinoma 17 years earlier. Functional impairment in cerebral cortical and subcortical structures was evaluated by studying the level of glucose metabolic activity at rest. Relative glucose metabolism was reduced in the prefrontal cortex contralateral to t he cerebellar lesion. Contralateral thalamic metabolism was reduced significantly. The results suggest that this phenomenon of “crossed cerebello‐thalamo‐cerebral diaschisis” is related to a funct ional depression of the cerebello‐thalamo‐cortical pathway.
