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.
