Multiple calcified aneurysms in coarctation of the aorta.

Abstract Two female patients in their sixth decades presented with multiple calcified aneurysms involving collateral thoracic arterial channels in association with coarctation of the aorta. The roentgen signs of coarctation of the aorta in the child and in the adult are briefly listed. The differential diagnosis of superior mediastinal calcifications is discussed, and the importance of careful inspection of the roentgenograms in a search for rib notching is emphasized. While rib notching is only suggestive of aortic coarctation, its combination with calcified aneurysms of the brachiocephalic arteries is practically pathognomonic.
