BILATERAL CEREBRAL INFARCTS
The patient was a 51 year old woman who had a cerebro-vascular accident resulting in a right hemiplegia 2 years prior to death and a second stroke resulting in a left hemiplegia 3 months prior to death. At necropsy she had severe generalized atherosclerosis and an old left ventricular myocardial infarct with overlying mural thrombus.
A coronal section of the cerebral hemispheres shows bilateral irregular cystic cavities in the territories of distribution of the right and left middle cerebral arteries. The cavities 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 are moderately atheromatous.
Her cerebral infarcts were probably embolic in origin.
