Contusions, recent, "contrecoup": Contusions (with or without laceration) are commonly observed at a site directly beneath the locus of injury to the skull. They are also often present over the inferior surfaces of the frontal and anterior temporal lobes, as in this slide. These areas constitute so-called "contrecoup" injury, i.e. injury at a distance from site of impact (not necessarily "opposite"). Because of the frequency of the finding of injury at these inferior frontal and temporal locations regardless of the site of primary injury, it is thought that the mechanism of their production is more likely a shearing effect produced by rotation of the inferior surface of the brain against the rough surface of the adjacent inner table of the skull.
