Background
- Aortitis caused by Mycobacterium tuberculosis
- Rare, with only 41 cases described from 1945 to 19991
- Pathogenesis may be from either:
- Contiguous spread from adjacent infection, such as tuberculous adenitis (more common)
- Hematogenous spread
Clinical Manifestations
- Can be present in either thoracic and abdominal aorta, mostly saccular and false aneurysms
- Persistent chest, abdominal, or back pain
- Palpable, pulsatile paraaortic mass
- Often have constitutional symptoms (from active tuberculosis) as well as lymphadenopathy
- Disseminated TB in about half of cases
- Fatal if not diagnosed and treated
Investigations
