Cerebral contusion in victims of fatal road traffic accident: frequency and association with other head injury lesions

A morphological study, macro and microscopical, was made of brain lesions in 120 victims of fatal road traffic accidents. Contusions of the brain were identified in 67 (55.8%) of the patients. The contusions especially affected the orbital surfaces of the frontal lobes (27.8%) and the temporal poles (19.8%). The recent brain contusion was associated with a skull fracture in 70.1% of the cases and with a diffuse axonal injury in 89.5%. These can be explained by the association of contact and inertia from the road traffic accidents. Old contusions were identified in six patients (5.0%).
