title: Round atelectasis in an elderly man: the role of thoracotomy.
abstract: In summary, a case of round atelectasis appearing subsequent to a pleural effusion in an elderly man 6 months after open heart surgery is reported. Although plain roentgenograms and linear and computerized tomography could help the physician make the diagnosis with confidence, a needle biopsy of the lesion at the very least or exploratory thoracotomy may sometimes still be justified for the properly selected patient.
