Anatomical classification of the INAA with associated calcified aortic plaques: type 0 saccular aneurysm without calcification; type 1 saccular aneurysm with calcified aneurysm neck; type 2 saccular aneurysm with aortic calcification far from aneurysm (more than 1 cm); type 3 saccular aneurysm with calcification within aneurysm wall; type 4 fusiform aneurysm with calcified intima; and type 5 fusiform aneurysm with peripheral calcification. Yellow arrows indicate calcified plaque on CT
