Broncholithiasis mimicking lung cancer.

A 64-year-old female patient was admitted to our outpatient clinic with pleuritic chest pain, non-productive cough, and dyspnea. She expectorated three stones (lithoptysis) before bronchoscopy. She underwent positron emission tomography-computed tomography, which revealed a hyper metabolic mass in the right upper lobe of her lung. Three months later, the mass formation appeared as a patchy consolidation in the first control thoracic computed tomography examination. In conclusion, postobstructive consolidation due to broncholithiasis, which is very rare, should be kept in mind in the differential diagnosis of hyper metabolic mass. The simplest incidental diagnostic finding of broncholithiasis is the rare lithoptysis.
