<prompt> A 14-year-old girl is rushed to the emergency room after receiving a gunshot wound to the head and is pronounced dead on arrival. If this child died due to an immediate blast effect of the penetrating wound, the autopsy would likely show herniation of the tonsils of the cerebellum into which anatomic space?Aqueduct of SylviusCentral spinal canalForamen magnumForamen of Magendie  <response>: Penetrating wounds produce hemorrhage and blast effects. The blast effect of a high-velocity projectile causes an immediate increase in supratentorial pressure and results in death because of impaction of the cerebellum and medulla into the foramen magnum. A low-velocity projectile increases the pressure at a more gradual rate through hemorrhage and edema. The other choices do not represent areas of herniation.Diagnosis: Bullet wound
