Vehicle-associated closed trauma-induced stroke in a 27-day-old girl.

Birth trauma, but not postnatal trauma, has been recognized as a cause of cerebral infarction in newborns. We report a case of cerebral infarction in a 27-day-old girl after a car accident. During the car accident, the child was properly restrained to the child's safety seat. The patient was admitted to the hospital for observation because of pronounced irritability. There were no focal neurological symptoms on admission. Twenty-eight hours after the accident, the child developed focal tonic-clonic seizures and mild right-sided hemiparesis. The seizures were successfully treated with phenobarbital at a dose of 30 mg per day. Computed tomography and magnetic resonance imagining performed on the second and third days after the accident, respectively, showed subdural hemorrhage in the occipital regions and cerebral ischemia in the left parieto-occipital region. Control imaging 10 days later showed signs of reperfusion. Persistent child irritability after head trauma is one of the indicating factors for performing an emergency computed tomography scan of the head.
