We investigated the role of CT in guiding fine-needle biopsy (FNB) in small (< 2 cm phi) lung lesions, reviewing 2109 CT-guided biopsies of peripheral lung nodules performed 1983 to 1993. "Peripheral" refers to non intrabronchial lesions, independent of the nodule position in the chest. Two hundred lesions < 2 cm phi were selected, 52 of them with complete clinical and surgical follow-up. This group was compared with 195 lung lesions > 2 cm phi for CT-guided FNB sensitivity, specificity and diagnostic accuracy. Cytologic specimens were positive for malignancy in 40/52 cases (76.9%) and negative in 12 (23.1%). Clinical-surgical follow-up confirmed all the positive cytologic findings (40 cases), while 2 of the extant 12 cases were false negatives (95.20% sensitivity, 100% specificity and 96.15% diagnostic accuracy). 158 of 195 nodules > 2 cm phi and with clinical-surgical follow-up (81.3%) were positive for malignancy and 34 were negative (17.43%) (98.75% sensitivity, 97.14% specificity and 98.46% diagnostic accuracy). Pneumothorax occurred in 33 patients (16.5%) with nodules < 2 cm phi as a complication of biopsy. Hemoptysis occurred in 15 patients (7.5%). In the whole group of lung lesions, the complications were pneumothorax in 80 patients (4.1%), hemoptysis in 199 (10.4%) and hypotensive vagal crises in 92 patients (4.8%). We conclude that CT is the best guidance for FNB also in small lung nodules, providing high sensitivity and specificity and low complication rates. Finally, the result of this procedure depends on the operator's skills.
