Abstract:
The coronary arteries of a 6-year-old Holstein-Friesian cow showed dysplastic lesions characterized by the following vascular changes: irregular, aneurysmal dilation; intimal fibrosis associated with myointimal cells; aberrant internal elastic lamina; oedema and mast cell infiltrates; and variation in the thickness of the media, including tortuosity with irregular dilation of the lumen of the artery and a plexiform structure formed from the right coronary artery.
