Objective To explore the significance of lung biopsy by CT-guided percutaneous paracentesis in the diagnosis of space-occupying lesions of the lung. Methods 52 patients with space-occupying lesions of the lung underwent lung biopsy by CT-guided percutaneous paracentesis with COOK 18-22G soft-tissue-cutting biopsy needles. Results 31(59.6%) cases were confirmed by pathological examination to suffer from primary pulmonary cancer, 5(9.6%) from tuberculosis and 14 (26.9%)from inflammatory pseudotumor. No definite diagnosis was made in 2(3.9%) patients, the accuracy of diagnosis was 96.1%. Minor pneumothorax occurred in 4 cases(7.7%) and blood sputum in 5cases(9.6%), but all did not need any treatment. Conclusions Lung biopsy by CT-guided percutaneous paracentesis is a safe and practical technique.
