To elucidate the clinical avaiability of FNAB, we reviewed retrospectively medical records of 30 patients who had infiltrative pulmonary lesion or pulmonary nodule or mediastinal mass, and got percutaneous fine needle aspiration biopsy using
Westcott
needle, 20~22 gauge, at the department of Pediatrics, Hanyang university hospital from July, 1986 to June, 1993.
@ES The obtained results were as follows:
@EN1) There were 30 patients, aged 6 months to 15 years.
2) There were 17 male patients and 13 female patients with sex ratio of 1.3:1
3) Among 30 cases, we discovered 16 cases of infiltrative lesions, 7 cases of pulmonary nodules and 7 cases of mediastinal mass lesions. In mediastinal there were 4 cases of anterior mediastinum and 3 cases of posterior mediastinum.
4) Overall success rate on fine needle aspiration biopsy was 60% (18/30). The success rate was 50% (8/16) in infiltrative lesions, 50% (8/15) in pulmonary nodules and 71% (5/7) in mediastinal mass lesions, respectively.
5) Eight infiltrative lesione were diagnosed as Pneumocystis carinii pneumonia. Five pulmonary nodules were diagnosed as aspergillosis (2 cases), tuberculosis (1 case), mucormycosis (1 case), lung metastasis of metastasis of neuroblastoma (1
case).
Five mediastinal mass lesions were diagnosed as teratoma (2 cases), lymphoma (1 case), malignant neurogenic tumor (1 case), ganglioneuroblastoma (1 case).
6) The complications occured in 20% (6 cases) among 30 procedures. All cases were due to pneumothorax: 3 cases spontaneously resolved, and 3 cases needed chest tube insertion. There were no death related with this procedures.
