iman it can happen. here is a little explanation from e medicine"".The primary injury occurs at the time of impact, either by a direct injury to the brain parenchyma or by an injury to the long white matter tracts through acceleration-deceleration forces. Direct injury to the brain parenchyma occurs as the brain is impacted on the bony protuberances of the calvaria or by penetration of the brain by bony fragments or a foreign body. in adults, in whom the brain is forced against the bony protuberances opposite the point of the impact, resulting in a countercoup injury. Intracranial hemorrhage may also result from shearing or laceration of vascular structures. Acceleration-deceleration forces cause shearing of the long white matter tracts, leading to axonal disruption and secondary cell death. ""

so theoritically its possible.
