Left Cerebral infarct

A coronal section of the cerebral hemispheres shows irregular cystic cavities in the territory of distribution of the right middle cerebral artery. The cavities of the infarct have irregular, yellow walls and show partial collapse. There is compensatory dilatation of the left lateral ventricle. On the posterior aspect, the arteries below the mammillary bodies were moderately atheromatous, although this is difficult to visualise macroscopically.
