Abstract

Cerebral infarcts rarely occur following head injury. Carotid artery dissection is usually proposed mechanism in such cases. We experienced a case of middle cerebral artery (MCA) infarct occurred just after head trauma without evidence of vascular abnormality. A 59-year-old male was transported to the emergency room immediately after traffic accident. He had right zygomatic fracture without neck injury. Left hemiparesis was noticed, and brain CT revealed hyperdense MCA sign in the right side. His neurologic status deteriorated over 2 days, and brain MRI showed total right MCA infarct with midline shift. Cerebral angiography was unremarkable. Two months later he had improved so much, but left hemiparesis with right MCA infarction re-developed. We suggest head trauma immediately can induce cerebral infarct without neck vessel injury, and in differential diagnosis of focal neurologic deficit after trauma, cerebral infarct as well as hemorrhage or contusion must be considered.
