A case of round atelectasis was reported. The roentgenographic features of round atelectasis are "comet tail sign" and localized pleural thickening. Round atelectasis appears as a mass like lesion that often mimics a pulmonary neoplasm. Recognition of this entity will help to prevent unnecessary procedures such as thoracotomy and pulmonary resection.
