Abstract
-
Rifampicin is a powerful agent for the treatment of pulmonary tuberculosis. However, it may induce several adverse effects, including rare cases of lung toxicity. Here, we report a case of rifampicin-induced interstitial pneumonitis. A 57-year-old woman diagnosed with cerebellar tuberculoma developed progressive dyspnea after the 5th day of anti-tuberculosis medication. Chest X-ray revealed newly developed ground glass opacities on both lower lung fields. Drug-induced pneumonitis was suspected and all anti-tuberculosis medications were halted. Transbronchial lung biopsy was consistent with desquamative interstitial pneumonitis. After clinical improvement, a rechallenge test with each anti-tuberculosis medication was attempted. No primary anti-tuberculosis drug except rifampicin triggered recurrence of symptoms, supporting a diagnosis of rifampicin-induced interstitial pneumonitis. Clinicians should be aware of this rare, but serious, side effect of rifampicin treatment.
