Ruptured Thoracic Aortic Aneurysm
Imaging findings
Unilateral pleural effusion (high attenuation) in a hypotensive patient. CT showing loss of aortic wall integrity and periaortic fluid.
Key takeaways
When performing CT for suspected PE in unstable patients, optimize contrast timing (e.g., triggering in the left atrium) to better visualize the aorta.
