This is a case of a 35-year-old-man found dead at home.\u00a0 His only known medical history was repair of a fractured finger from falling from a bicycle at the age of 32.\u00a0 His blood pressure was elevated at that time, but he was noted to be in pain.\u00a0 At autopsy there were 380 cc of liquid blood in the pericardial space.\u00a0 The heart was not enlarged, but there was an obvious area of balooning and thinning of the proximal ascending aorta, with perforation.\u00a0 The diameter of the aorta at the site of perforation was 4.3 cm, while the diameter immediately above it was 2.1 cm:<\/p>\n
