Abstract

We report distinctive diffusion-weighted magnetic resonance image (DWI) findings in a 65-year-old man with clinically diagnosed Creutzfeldt-Jakob disease (CJD). Four weeks before admission he developed general weakness and febrile sense which were followed by progressive dementia, ataxia, and choreo-athetoid movement of the right hand. T2-weight-ed magnetic resonance image (MRI) showed subtle high signal intensities only in the left basal ganglia, whereas DWI demonstrated marked hyperintensities in multiple regions including the left basal ganglia and left cerebral cortex. Five weeks after the onset of symptoms, he was noted to have myoclonus and characteristic electroencephalographic changes consisting of periodic triphasic sharp waves. In our patient, high signal changes on the DWI preceded myoclonus and typi-cal EEG findings, a result suggesting that DWI may be useful in the early premortem diagnosis of CJD.
