Abstract
Tuberculous aortitis is difficult
to diagnose, but early treatment may limit the progression of
tuberculosis aortitis, which may cause aortic stenosis or pseudoaneurysm
formation if untreated. We
provided antituberculous therapy on suspicion of tuberculous aortitis,
despite the lack of definitive diagnosis, and obtained a favorable
outcome.
Keywords: tuberculous aortitis, tuberculosis, aortitis; antituberculous
therapy
A 22-year-old man from Nepal presented with a one-month history of fever
and weight loss. He had no previous history of illness or medication
use. Apart from an elevated serum C-reactive protein level (1.40 mg/dL),
his physical examination and laboratory test results were unremarkable.
Contrast-enhanced computed
tomography (CT) showed a pericardial effusion, mediastinal
lymphadenopathy, mild right lower-lobe lung consolidation, and ascending
aortitis (Fig. 1a–c). The T-SPOT.TB test result was positive.
Bronchoalveolar lavage and mediastinal lymph node biopsy were performed
because of suspected active tuberculosis. Although the
tuberculous culture and polymerase
chain reaction tests for Mycobacterium tuberculosis were
negative, we commenced treatment with isoniazid, rifampicin,
pyrazinamide, ethambutol, and prednisolone (60 mg/day, tapered weekly).
Two months later, the patient’s body temperature and weight normalized,
so ethambutol, pyrazinamide, and prednisolone were discontinued.
Isoniazid and rifampicin were continued for an additional 7 months.
After 9 months of treatment, contrast-enhanced CT showed resolution of
the aortitis (Fig. 1d), pericarditis, mediastinal lymphadenopathy, and
lung consolidation. Early therapy may limit the progression of
tuberculosis aortitis, which may cause aortic stenosis or pseudoaneurysm
formation if untreated,1 so we commenced drug therapy
despite the lack of a definitive diagnosis, and obtained a favorable
outcome.
