Cystic Lung Changes in a Patient With Pulmonary Tuberculosis

A 32-year-old male had complained of a dry cough on and off for 1 year. Chest radiography revealed reticular infiltration of bilateral lungs. Chest computed tomography showed multiple thin-walled cystic lesions of bilateral lungs with a scattered tree-in-bud appearance. Histological diagnosis obtained via a video-assisted thoracoscopic lung biopsy indicated pulmonary tuberculosis. The cystic lesions regressed after antituberculous chemotherapy. Active pulmonary tuberculosis presenting as multiple cystic lung lesions on computed tomography is very rare. Here, we report the computed tomo-graphic findings for this patient and review the literature.
