Background:  Penetrating injury to the head, with the exception of missile injuries, is rare owing to thickness of skull bones. Orbital and temporal areas are comparatively vulnerable to penetrating injuries due to their relative thinness. Objective: We presented a case in which a man was killed by forcefully thrusting a screw driver through left temporal bone into his cranial cavity and injured the brain. Case presentation:  We presented a case of a 44-year-old man who was stabbed with a screw driver in his head.   The screw driver was seen embedded in his head. Plain radiography and computed tomography (CT) of the head were done to assess the extent of brain damage. Conclusion:  In this study, we discussed the the peculiarity of this case which lays in the fact that screw driver as a stabbing weapon in the head is very rarely used. Skull bone, at site of injury, was very thin with less than 2 mm thickness and even transparent to light. This was unfortunate for both the assailant and the deceased. We also emphasized the indispensable role of imaging in the initial assessment of patients with head trauma.
