Description
This shows the brain stem and cerebellum. On the right vertebral artery there is a ruptured
aneurysm marked by the arrow, with surrounding subarachnoid haemorrhage. The right
cerebellar tonsil is prominent but it has not been cut, so one is not sure whether there is bruising
indicative of coning or not. A bilateral carotid arteriogram did not demonstrate the aneurysm and
death occurred before the vertebral system could be investigated.
