This shows the under-surface of the brain, with the basal portions of the temporal lobes cut away.
The basilar artery is tortuous and enlarged in a nodular fashion; the left vertebral artery can be
seen on the right-hand side of the specimen, but the right vertebral artery cannot be seen. There
is extensive atheroma of the middle cerebral arteries. Inspection of the whole specimen shows
neither haemorrhage nor infarction. No history is available.
