TRAUMATIC CEREBRAL HEMORRHAGE

We shall present a series of fatal cases of cranial traumatism studied at autopsy, particular attention being paid to those showing multiple miliary hemorrhages not immediately related to the traumatic focus and constituting the type known as multiple concussion hemorrhages. We shall also give a clinical review of a series of cases of concussion presenting late evidence of severe damage to the brain. The effects produced by concussion of the brain have been described by many writers. In 1860, Bauchet, 1 studying the mechanism of traumatic lesions of the brain and the oscillations of the cranium, thought that these oscillations must be transferred to the brain mass, and that the insult may be carried to the point of more or less considerable derangement of the molecules of the brain. When confined to certain limits and under certain conditions, the brain substance will resist the external violence and will not be
