AbstractWe reviewed the results of US-guided fine-needle biopsies of peripheral pulmonary, pleural, mediastinal and chest wall lesions in 200 patients. Sufficient material for cytological analysis was obtained in 95%, 92%, 96% and 100%, respectively. Sensitivity was 88%, 94%, 96%, 100% and specificity 89%, 100% and 100%, respectively. The ratio of false-negative results was 7%. A cutting needle biopsy was additionally performed in 24 patients. All but two of the histological samples (92%) were adequate for diagnostic purposes and a correct diagnosis was established in 86% (19/22) of these. 8 patients (4%) with pleural or pulmonary targets had minor complications (5 pneumothorax, 3 haemoptysis), which did not require treatment. Cutting needle biopsies and biopsy of mediastinal lesions proved safe. Due to the many advantages US may be considered for guidance in peripheral larger-sized pulmonary lesions, particularly those abutting the pleura, and also in pleural, thoracic wall and mediastinal masses.
