title: [Usefulness of CT-guided aspiration biopsy in combination with rapid cytology for diagnosis of benign pulmonary lesions].
abstract: OBJECTIVE
  To evaluate the diagnostic accuracy of computed tomography (CT)-guided aspiration biopsy in combination with rapid cytology for benign pulmonary lesions.
  
  
  METHODS
  We performed percutaneous aspiration biopsy under CT guidance in combination with a rapid cytologic examination in 91 patients with pulmonary lesions. A 21-gauge modified Menghini needle coaxially placed through an 18-gauge needle was used in this procedure. Thirty-one lesions that were confirmed as a benign pulmonary lesion histologically, serologically, bacteriologically and/or clinically were evaluated in this study.
  
  
  RESULTS
  In 28(90.3%) of 31 lesions, sufficient material for cytologic diagnosis was obtained from the aspiration biopsy. Specific benign diagnosis for benign disease was obtained in 13 lesions (41.9%), while nonspecific diagnosis for benign disease was obtained in 15 lesions (48.4%). The overall accuracy of the rapid cytological examination was 90.3%. Pneumothorax developed in 17 patients (54.8%), with 7 patients (22.6%) requiring chest tube drainage. Only one patient complained of mild hemoptysis, which subsided with hemostatic agents.
  
  
  CONCLUSIONS
  Percutaneous aspiration biopsy combined with a rapid cytologic diagnosis provides a high degree of accuracy in the diagnosis of benign pulmonary lesions.
