title: Magnetic resonance imaging of sequelae of temporal lobe herniation secondary to traumatic acute subdural hematoma: Kernohan's notch and posterior cerebral artery territory infarctions contralateral to the supratentorial lesion--case report.
abstract: A 16-year-old girl presented with left hemiparesis and right oculomotor nerve paresis due to temporal lobe herniation resulting from a traumatic acute subdural hematoma secondary to a head injury. Computed tomography revealed a subdural hematoma in the right frontotemporal regions and midline structures shifted to the left. She became comatose and underwent an emergency operation. The hemiparesis and newly manifested homonymous hemianopsia on the right side persisted after surgery. Postoperative magnetic resonance imaging showed Kernohan's notch in the cerebral peduncle and infarctions in the occipital lobe and posterolateral part of the thalamus on the left side, contralateral to the supratentorial lesion.
