title: Two cases of rounded atelectasis presenting after coronary artery surgery.
abstract: Rounded atelectasis developed in two patients after coronary artery bypass grafting. Although both lesions led to the suspicion of a primary pulmonary tumor on initial assessment, malignancy was excluded by biopsy and radiologic observation in the first patient and excision biopsy in the second.
