Posttraumatic cerebral infarction is a rare complication and is an indicator of poor clinical outcome of head-trauma in spite of appropriate medical and surgical interventions. Cerebellar infarction following head trauma is also very rare and only a few reported cases are available in literatures. A 2-year-old child sustained head injury in a car accident and underwent surgery because of cerebral contusions and acute subdural hematoma. Cerebellar infarction was revealed in control imaging and she died on the third day after surgery.
