Summary
Tuberculosis can affect arteries, causing pseudoaneurysms. This case highlights a tuberculous iliac artery pseudoaneurysm presenting as fever, emphasizing the need for considering tuberculosis in mycotic pseudoaneurysm diagnoses.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Radiology
Background:
- Tuberculosis (TB) is a systemic infectious disease with diverse clinical presentations.
- Arterial involvement by Mycobacterium tuberculosis is rare but can lead to serious complications.
- Contiguous spread from an infected focus is a common pathway for arterial TB.
Observation:
- A case of tuberculous pseudoaneurysm of the iliac artery is presented.
- The patient initially presented with fever of unknown origin.
- Abdominal CT-scanning was crucial for diagnosis.
Findings:
- Postoperative microbiologic and microscopic studies confirmed tuberculous etiology.
- Despite early antituberculous therapy, the patient experienced a fatal non-infectious abdominal aortic rupture.
- This case underscores the diagnostic challenge of tuberculous pseudoaneurysms.
Implications:
- Clinicians should include tuberculosis in the differential diagnosis for mycotic pseudoaneurysms.
- Early and accurate diagnosis of arterial tuberculosis is critical for patient management.
- Further research into the vascular manifestations of tuberculosis is warranted.
