Background and Aim: Necrotizing pneumonia is an uncommon disorder with a high mortality rate. Different factors are involved in the incidence of this disease.
Case: A 73 years old man was admitted to the hospital with a chief complaint of dyspnea and productive cough. Chest x-ray showed a consolidation in the lower lobe of the left lung and a CT-scan revealed a cavity in the lingula. Bronchoscopy was performed and examination of bronchoalveolar lavage (BAL) fluid was positive for acid-fast bacilli. Anti-tuberculosis drugs were started for the patient.
Conclusion: Our case demonstrates a rare manifestation of tuberculosis associated with lung necrosis and cavitation, which emphasizes the necessity of examination and work-ups for mycobacterium TB in patients with drug resistant chronic pulmonary disease.
