Abstract

Kernohan's notch is one of the commonly described false localizing signs in clinical neurology. The lesion has been clearly demonstrated by MRI and is shown as hyperintense lesion of the cerebral peduncle on T2-weighted images. The lesion is best demonstrated on coronal imaging. We describe the lesion in a 56-year-old male with chronic subdural hematoma. The neurological sings disappeared after evacuation of the SDH.

Keywords
