Objective To explore the diagnostic value of CT-guided percutaneous lung biopsy for pulmonary solid lesions.Methods CT-guided percutaneous lung biopsy was performed in 97 cases of pulmonary solid lesions. The lesions were 2~10 cm (mean, 4.2 cm) in diameter, and the distance to the pleura was 0~8 cm (mean, 3.4 cm). Results Confirmative diagnoses were achieved in 73 cases of lung cancer and 21 cases of benign lesions (inflammation, tuberculosis, or sarcoidosis). The diagnostic rate was 96.9% (94/97). The biopsy could not indicate the accurate diagnosis in 3 cases, 2 of which were identified as having squamous cell carcinoma by operation, and 1 of which was followed for 2 years with no changes. Postoperative complications included 8 cases of pneumothorax, 2 cases of hemothorax, and 2 cases of emptysis. Conclusions CT-guided percutaneous lung biopsy is safe and offers a high diagnostic rate, especially suitable for lesions near the pleura.
