Overview DSA brain of an asymptomatic patient in posterior-anterior configuration.
Left: a fusiform ECAA in the right ICA and saccular shaped ECAA in the distal part of the RICA. Right: a fusiform dilated ECAA in the left ICA and a saccular shaped IA of the anterior communicating artery (all indicated by white arrows). Abbreviations: DSA = digital subtraction angiography, ECAA = extracranial carotid artery aneurysm, ICA = internal carotid artery, IA = intracranial aneurysm.
