Imaging findings
Plane film shows a large mass blotting out the right heart. CT reveals a massive ascending aortic aneurysm. Pathology showed no cystic medial necrosis or bicuspid valve, but the media had been "eaten away," suggesting old healed vasculitis. Patient also had incidental aortic regurgitation.
Key takeaways
Large ascending aortic aneurysms can be incidental findings. While commonly associated with cystic medial necrosis or bicuspid valve, this case showed an unusual etiology of healed non-specific vasculitis. Syphilitic vasculitis was considered but couldn't be confirmed without special stains.
