Extensive calvarial, skull base and facial fractures. Traumatic subarachnoid and intraventricular haemorrhage. Scattered petechial intraparenchymal haemorrhages including within the midbrain consistent with shearing injury. Cerebral oedema with loss of grey-white differentiation, on the left in particular, possibly due to dissection of the left ICA at the skull base due to fractures. There is a nice example of the 'white cerebellum sign' of cerebral oedema which is an extremely poor prognostic feature. This patient died shortly after.
