title: Atypical gunshot exit defects to the cranial vault.
abstract: Cranial exit wounds typically display external beveling, however, variation has been noted in the literature due to keyhole phenomena and pre-existent fractures. Two cases of atypical exit morphology are presented with features mimicking blunt trauma. In both instances radial fractures created by the exiting impact allowed passage without producing exit beveling. A working knowledge of the biomechanics of bone fracture, radiographs and low power microscopy are essential elements for the proper interpretation of such exit wound fractures.
