Vascular Pathology: Neurovascular Disease: Subarachnoid Haemorrhage from a Ruptured Berry Aneurysm

An autopsy specimen from a 43 year old man found dead in a lavatory at his place of work. He had not consulted a doctor or complained of any illness for over 15 years. At post mortem, there was evidence of hypertension with concentric hypertrophy of the left ventricle, in a heart weighing 420g. No significant atheroma was seen in the vascular system. The under surface of the brain shows widespread subarachnoid extravasation of fresh blood. Much of the blood clot has been cleared away to show a ruptured berry aneurysm originating from the anterior communicating artery.
