Area of Science:

• Cardiology
• Vascular Surgery
• Gastroenterology

Background:

• A 70-year-old male with a history of aortitis presented with symptoms of upper gastrointestinal bleeding.
• Initial investigations included endoscopy, which revealed blood but no definitive bleeding source.

Observation:

• Computed tomography angiography (CTA) identified an eroded aortic aneurysm at the site of known aortitis.
• The erosion resulted in bleeding into the lung and pleural space.

Findings:

• The case highlights a rare presentation of aortitis complicated by aortic aneurysm erosion and gastrointestinal hemorrhage.
• Endoscopy can be misleading in cases of aortoenteric fistula or aortopulmonary fistula.

Implications:

• Early diagnosis via advanced imaging like CTA is crucial for managing aortitis complications.
• Thoracic endovascular repair offers a potentially life-saving intervention for such critical vascular events.
