Intracranial penetrating injury by screw driver: a case report and review of literature.

Penetrating injury to the head, with the exception of missile injuries is rare owing to thick calvarium. Orbital and temporal areas are comparatively vulnerable to penetrating injuries, due to their relative thinness. A case is presented in which a man killed his wife by forcefully thrusting a screw driver into her cranial cavity. The deceased presented to the hospital with the screw driver embedded in her head. She was declared as 'brought dead on arrival' at the emergency of the hospital. Pre-autopsy plain radiography and Computed Tomography (CT) of the head were done to assess the extent of brain damage. The peculiarity of this case lies in the fact that screw driver as a stabbing weapon in the head is very rarely used. In such cases, there is a need to perform radiography and CT with the weapon in-situ for better interpretation on injuries. In this paper role of radiography and CT in intra cranial penetration is discussed with review of literature.
