Kernohan’s Notch: A Forgotten Cause of Hemiplegia—CT Scans Are Useful in This Diagnosis

<table>Schematic representation of Kernohan’s notch. Demonstrated here are a subdural hematoma and uncal herniation on the same side. Notching of the midbrain is seen on the opposite side (Kernohan’s notch). This damages the contralateral pyramidal tract fibers in the midbrain and causes hemiparesis on the side of subdural hematoma.</table>
