Abstract:
Tuberculosis (TB) is an uncommon cause of mycotic aneurysm. Studies have described tuberculous aneurysm of the entire aorta. Tuberculous pericarditis can cause life-threatening complications such as pseudoaneurysm in the aorta. Aneurysm of the aorta has been associated with disseminated TB, vertebral or mediastinal TB, and in patients who had a history of TB. The thoracic aorta is the most common site for tuberculous aneurysms due to its proximity to the lungs and mediastinum. Accurate diagnosis and quick intervention can be life-saving in these cases. We discuss here a rare case of pseudoaneurysm of the arch of aorta associated with pericardial TB and pericardial and pleural effusion.
Insights
Tuberculosis (TB) is a rare cause of aortic aneurysms. This case highlights a pseudoaneurysm of the aortic arch linked to tuberculous pericarditis, emphasizing the need for prompt diagnosis and intervention.
Area of Science:
- Cardiology
- Infectious Diseases
- Radiology
Background:
- Tuberculosis (TB) is an infrequent cause of mycotic aneurysms, with documented cases involving the entire aorta.
- Tuberculous pericarditis can lead to severe complications, including aortic pseudoaneurysms.
- Aortic aneurysms are associated with disseminated TB, vertebral or mediastinal TB, and prior TB history.
Purpose of the Study:
- To report a rare case of aortic arch pseudoaneurysm secondary to tuberculous pericarditis.
- To underscore the diagnostic challenges and critical importance of timely intervention in such cases.
Main Methods:
- Case report detailing a patient with pseudoaneurysm of the aortic arch.
- Review of literature on tuberculous aneurysms and their association with pericardial TB.
Main Results:
- The thoracic aorta is the most common site for tuberculous aneurysms due to anatomical proximity to pulmonary and mediastinal TB.
- Accurate and rapid diagnosis is crucial for effective management and improved patient outcomes.
Conclusions:
- Pericardial tuberculosis can manifest as a pseudoaneurysm of the aortic arch.
- This presentation necessitates a high index of suspicion for TB in patients with aortic aneurysms, especially with concurrent pericardial or pleural effusions.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
