CT-guided fine needle aspiration biopsy (CT-FNAB) was performed in 13 patients, because it was difficult to obtain diagnostic material by bronchofiberscopic or fluoroscopic biopsy. The age range was 22 to 76 year (average 56.2); 10 were male and 3 were female. The tumor size was 15 to 30 mm (average 25.3 mm). We used the Sure-cut needle (21 gauge). In the 13 patients with small pulmonary nodules, 11 cases of lung cancer were confirmed by needle biopsy (100 %; 11 out of 11 cases), and 2 cases of hamartoma were confirmed by surgery.<BR>Of the 11 lung cancers, 8 were surgically resected and 3 were treated with combination chemotherapy. In one of the 11 patients (7.7 %), pneumothorax occured after needle aspiration biopsy. No recurrence of tumor in the CT · FNAB needle tract was found during the 4-43 month follow-up period (average 25.1 months). We conclude that CT-guided fine needle aspiration biopsy is very useful in lung cancer patients, when it is difficult to obtain diagnostic materials by bronchoscopic or fluoroscopic biopsy.
