Delayed chest radiographs and the diagnosis of pneumothorax following CT-guided fine needle aspiration of pulmonary lesions

We prospectively studied 64 consecutive patients on whom computerized tomog raphy-guided fine needle aspirations (CT-FNA) of pulmonary lesions were per formed to determine whether obtaining a delayed chest radiograpy (CXR) afte r CT-FNA is helpful in the diagnosis of post-procedure pneumothorax (PTX). Two of the 64 patients developed a delayed PTX. Only one of the patients wi th a delayed PTX required chest tube drainage. If patients have no evidence of a PTX immediately after a CT-FNA by CT scan then a delayed CXR adds lit tle to care of these patients.
