Abstract:
Objective To assess the diagnostic value of the CT-guided percutaneous lung biopsy in diffuse lung diseases. Methods CT-guided percutaneous lung biopsy was performed using 18G or 20G biopsy needle in 68 patients with diffuse lung diseases. The main imaging changes of these patients included network of diffuse nodular or nodular, diffuse reticular lines shadow and diffuse ground-glass density in the lungs. Results Punctures were successful in all 68 patients, and the diseases were clearly diagnosed, including 19 patients with malignant (9 bronchioloalveolar carcinoma and 10 metastatic carcinoma) and 49 with benign (27 disseminated pulmonary tuberculosis, 8 sarcoidosis, 7 silicosis and coal worker's lung, 2 interstitial pneumonia, 4 pulmonary alveolar proteinosis allergic and 1 pneumonia) lesions. The major complications of puncture were pneumothorax and bleeding, and the incident rate of complications was 17.65%. Conclusion CT-guided percutaneous lung biopsy is a useful, safe technique with low complications, high accuracy rate for the diagnosis of diffuse lung diseases.
