摘要：

The reported frequency of false-negative diffusion-weighted magnetic resonance imaging (DWI) cases is 3.5%-25%. However, territorial stroke (eg, middle cerebral artery territory) with negative DWI is very rare. We report a case of territorial ischemic stroke persisting for 5 days without identification of a definite lesion on DWI but with decreased perfusion on perfusion computed tomography in a patient with underlying severe leukoaraiosis. This case suggests that severe leukoaraiosis might be responsible for the negative finding on DWI in acute ischemic stroke.
