Percutaneous CT-guided core needle biopsy versus fine needle aspiration in diagnosing pneumonia and mimics of pneumonia.

The purpose of this study was to determine the diagnostic value of percutaneous core needle biopsy (CNB) relative to fine needle aspiration (FNA) in patients with pneumonia and pneumonia mimics. In this prospective study we present our experience with 48 thoracic FNAs and CNBs carried out on 48 patients with pneumonia and pneumonia mimics. Samples were obtained from all patients using both CNB (with an automated 18-G core biopsy needle and a gun) and FNA (with a 22-G needle). A specific diagnosis was made in 10/48 cases (20.83%) by FNA and in 42/48 (87.5%) by CNB. The main complications encountered were pneumothorax (n = 4) and hemoptysis (n = 2), yielding a total complication rate of 12.5%. We concluded that CNB using an automated biopsy gun results in a higher diagnostic accuracy for pneumonia and pneumonia mimic biopsies than FNA. Complications should be considered and proper patient observation should follow the procedure.
