Impending rupture of nonaneurysmal bacterial aortitis: CT diagnosis

Abstract:
The CT appearance of mycotic abdominal aortic aneurysms leading to eventual rupture has been well described. On the other hand, ruptured nonaneurysmal bacterial aortitis has not been demonstrated in the CT literature. We present two cases with subsequent rupture documented on CT. The characteristic findings of periaortic density and adjacent gas collection should suggest the diagnosis of acute aortic infection. This may herald impending rupture, even in the absence of aneurysmal dilatation, and should direct therapy accordingly.
Insights
Ruptured bacterial aortitis without aneurysm can be identified on CT scans. Key signs include periaortic density and gas, suggesting infection and potential rupture.
Area of Science:
- Radiology
- Infectious Diseases
- Vascular Surgery
Background:
- Mycotic abdominal aortic aneurysms (MAAAs) and rupture are well-documented in CT literature.
- Ruptured nonaneurysmal bacterial aortitis has not been previously demonstrated on CT.
- Acute aortic infections can lead to serious complications.
