Pulmonary Tuberculosis Reactivation: Triggered by the Descent in Altitude?

High altitudes are linked to decreased rates of pulmonary tuberculosis infection, disease and mortality. However, its relevance as a trigger for pulmonary tuberculosis reactivation in immunocompetent patients is not documented. A 28-year-old healthy Nepalese female was admitted in the emergency department with sudden left pleuritic back pain with shortness of breath, two weeks after arriving in Lisbon, having arrived from Kathmandu and undergone a change in altitude of 1400 metres.
