Crossed cerebellar diaschisis in positron emission tomography/computed tomography with (¹⁸F) fluoro-D-glucose in a 53-year-old woman with a history of glioblastoma multiforme in the left temporal lobe, after treatment for recurrence. The patient had initially been treated with surgery and radiation and, 2 years later, with γ-knife and chemotherapy for recurrence. The uptake of (¹⁸F) fluoro-D-glucose is diffusely decreased in the left cerebral hemisphere and in the contralateral cerebellar hemisphere
