The right thorax was slightly full, and the right lung transparency was increased. Multiple cystic translucent areas were seen in the right middle and lower lung fields, with an area of about 46 × 67 mm, and the boundary was not clear. The lung markings of the left lung increased and thickened, and a few patchy blurred shadows were seen in both lungs, especially in the lower left lung, and the size, shape, and position of the left hilum were not abnormal; the trachea, mediastinum, and heart shadows shifted slightly to the left. The mediastinum was not widened. Consider cystadenoma malformation (type I).
