Value of ct-guided fine needle aspiration in solitary pulmonary nodules with negative fiberoptic bronchoscopy

Abstract

The usefulness of fine needle aspiration (FNA) with CT-guidance was evaluated in the diagnosis of solitary pulmonary nodules (SPN) following negative fiberoptic bronchoscopy in 84 patients. The records were analyzed for all patients with SPN who had undergone chest FNA in the years 1988 to 1990, showing previous nondiagnostic fiberoptic bronchoscopy. A final diagnosis was made by biopsy (transbronchial, thoracotomy or necropsy), response to therapy or follow-up of the lesions. The patients had medium-sized lesions, 2.87 ± 1.11 cm, adherent to the pleura in 62% In the diagnosis of malignancy FNA showed 76% sensitivity, 100% specificity, 100% positive predictive value, 52% negative predictive value and 81% accuracy. These results were correlated with histology in 84% of the cases. One pulmonary hemorrhage, which resolved spontaneously, and 12 cases of pneumothorax, requiring a thoracic tube in 4 patients, were noted. © 1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
