OBJECTIVE: CT-guided transthoracic biopsy is a well-established method in the cytologic or histologic diagnosis of pulmonary lesions. The knowledge of its diagnostic performance and complications for cavitary pulmonary lesions is limited. The purpose of this study was to determine the diagnostic accuracy and safety of CT-guided fine needle aspiration biopsy (FNAB) in cavitary pulmonary lesions. MATERIALS AND METHODS: 102 consecutive patients with pulmonary cavitary lesions received CT-guided FNAB with use of an 18-gauge (n=35) or 20-gauge (n=67) Chiba for histology diagnosis. The sensitivity, specificity, and diagnostic accuracy of FNAB were calculated as compared with the final diagnosis. Complications associated with FNAB were observed. The diagnostic accuracy and complications were compared between patients with different lesion sizes and different cavity wall thickness. RESULTS: The overall sensitivity, specificity, and accuracy of FNAB were 96.3%, 98.0%, and 96.1%, respectively. The sensitivity, specificity, and diagnosis accuracy in different lesion size (< 2 cm vs ≥ 2 cm), or different cavity wall thickness (< 5mm vs ≥ 5 mm) were not different (P>0.05; 0.235). More nondiagnostic sample was found in wall thickness <5mm lesions (P=0.017). Associated complications included pneumothorax in 9 (8.8%) patients and alveolar hemorrhage in 14 patients (13.7%) and hemoptysis in 1 patient (1%). No different rate of complications was found with regard to lesion size, wall thickness, length of the needle path and needle size (P>0.05). CONCLUSION: CT-guided FNAB can be effectively ad safely used for patients with pulmonary cavitary lesions.
