The specimen shows the left cerebral hemisphere, swollen and encroaching on the territory of
the right hemisphere. Centrally there is haemorrhagic infarction, largely apparent in the grey
matter while, at the periphery, the cortex is pinkish in colour and not as obviously infarcted as the
central convolutions. The base of the brain has been dissected to expose the left middle cerebral
artery, which contains thrombus.
