OBJECTIVE: To evaluate the results of computed tomography (CT)-guided fine
needle aspiration (FNA) cytology following negative fiberoptic bronchoscopy
and sputum cytology.
STUDY DESIGN: Retrospective study of 64 patients who underwent CT-guided ne
edle aspiration of lung opacities otter one year. Following a re review of
the CT studies, patients were selected according to image characteristics o
f a primary neoplasm and pleural effusion in eases with pleural lesions. Th
e lesions were classified into three categories-intrapulmonary and peripher
al pulmonary pleuropulmonary and pleural-and were localized and aspirated u
nder CT using a fine needle (22-23 gauge)for obtaining cellular material. L
esions diagnosed as benign on FNA cytology were followed by serial CT scans
for a period of two years at sis-month intervals.
RESULTS: Thirty-nine of 64 (61%) lesions were diagnosed as malignant on FNA
cytology and 25 of 64 (39%) as benign. There was one false negative case.
There were no serious complications from the procedure.
CONCLUSION: FNA tinder CT guidance may be applied as the initial procedure
in the diagnosis of peripheral malignant pulmonary lesions, rendering a hig
h diagnostic yield.
