Percutaneous management of intrapulmonary air and fluid collections.

The radiologist's role in the management of intrapulmonary air and fluid collections is becoming more important. Improvements in percutaneous interventional techniques now allow the radiologist to offer patients an alternative treatment option with less morbidity and mortality than surgical resection. The use of CT allows optimal catheter placement and enables safe and effective percutaneous evacuation of intrapulmonary collections. In summary, image-guided percutaneous catheter drainage should (1) be the initial procedure performed to diagnose and treat lung abscesses not responding to conservative therapy; and (2) because of its effectiveness and safety, be considered as a treatment option in the management of symptomatic patients with intrapulmonary mycetomas.
