Description
		
A coronal section of brain through the anterior parietal area, showing marked swelling of the 
white matter and, to a lesser extent, of the grey matter on the left with compression of the left 
lateral ventricle. Mounted with the specimen is the left carotid artery, showing occlusion by 
thrombus of the internal carotid artery from its origin. There is an atheromatous plaque 
extending downwards from the level of the bifurcation in the common carotic, and an 
atheromatous plaque can be seen in outline in the upper-third of the portion of the internal 
carotid artery present. 
		 History
		
This man, at the age of 67, was admitted to hospital with urinary retention, and 
underwent a transurethral resection of the prostate. In the postoperative period he had difficulty 
breathing, attributed to asthma and emphysema, and approximately fourteen days after the 
operation his condition deteriorated rapidly, and he was shown to have a flaccid paralysis on the 
right side. At autopsy, the internal carotid artery on the left was thrombosed from its origin to the 
base of the skull.
