A 56-year-old man with chronic lymphocytic leukemia, progressive multifocal leukoencephalopathy, and a dense left homonymous hemianopia had18F-fluorodeoxyglucose positron emission tomography.

To our knowledge, this is the first demonstration of cerebral and cerebellar hypometabolism due solely to white matter disease.
