case_images: Chest X-ray: Pulmonary patterns in the left lung field have disappeared, and the left diaphragm has been pushed down. This is considered to be a finding of severe lung collapse.

case_images: Following the 14th course, the patient complained of palpitations and malaise, and chest radiography and computed tomography revealed a collapsed left lung (Fig. 1, 2a, b).
case_images: Chest CT. a Collapse of the left lung in the left upper lung field and bulla on the left apical mediastinum side. The yellow arrows indicate the bulla. b Collapse of the left lung in the left lower lung field. Multiple pulmonary metastases were observed in both lungs. Interstitial pneumonia was also observed. The yellow arrows indicate multiple pulmonary metastases and interstitial pneumonia in the non-collapsed right lung. CT, computed tomography.

case_images: Following the 14th course, the patient complained of palpitations and malaise, and chest radiography and computed tomography revealed a collapsed left lung (Fig. 1, 2a, b).
case_images: Operative findings. a Multiple lung tumors. b Tumor with suspected air leakage. c The tumor was covered with a TachoSil  tissue-sealing sheet.

case_images: Thoracoscopic observation under general anesthesia revealed multiple nodules on the lung surface (Fig. 3a), suggesting lung metastasis from breast cancer. Although the site of the air leak could not be identified, a tumor in the left lower lobe appeared to rupture, and that area was estimated to be the cause of the air leak (Fig. 3b). The tumor was covered with a TachoSil  tissue-sealing sheet (Fig. 3c).
