Case report demonstrates bronchopleural fistula localization using retrograde methylene blue instillation, highlighting an effective diagnostic tool when conventional imaging modalities fail.
Bronchopleural fistulas (BPF) resulting from pulmonary resection, radiation, or a direct tumor mass effect are associated with significant morbidity, reduced quality of life, and increased risk of mortality. Diagnosing BPF can be challenging, even with computed tomography, magnetic resonance imaging, and bronchoscopy. We report a case in which retrograde methylene blue instillation during bronchoscopy successfully confirmed the diagnosis of BPF.
