Preoperative CT and newly formed pulmonary cyst in Case 1. Preoperative CT showing a nodule of 23 mm in the middle of the right lower lobe (arrow). CT reveals few fibrotic changes; however, the patient was diagnosed with interstitial pneumonia by histopathology of the resected lung (A). Postoperative CT performed on POD 17 shows a newly developed pulmonary cyst at the upper interlobular surface of the middle lobe with subcutaneous emphysema and pneumomediastinum (axial section: B, coronal section: C). A broad-based pulmonary cyst is observed during reoperation (arrows) (D)
