title: Rounded atelectasis that disappeared after bronchoscopy.
abstract: We describe a 70-year-old man who presented with a round opacity that disappeared after bronchoscopy. Chest computed tomograms (CT) showed a round opacity in the left lower posterior lung field. Brushings and washings of the left B10 through bronchoscope yielded neither malignant cells nor acid fast bacilli. The patient was diagnosed as having a benign tumor and was not medicated. Chest CT 1.5 months after bronchoscopy showed that the round opacity had disappeared. Although this course was unusual, this radiopacity was quite typical of round atelectasis on the basis of CT appearance.
