We describe the case of an elderly male patient who presented with a proximal descending aortic aneurysm after a motorcycle accident in 1977. We concluded that the aorta had been transected at that time. In a rather unconventional manner. the aneurysm developed a circumferential layer of calcification that provided mechanical stability and likely prevented further degeneration. https://jalyttlers.shop/product-category/scouring-sponge/
