摘　　要：Background: Colorectal cancer is one of the most common cancer types, frequently metastasizing into the lungs. Treatment options have been vastly improved over the last years. With the increasing use of targeted therapies, novel and rare adverse effects can be seen. Case Presentation: A 43-year-old woman presented in our oncology department with chest pain and dyspnea. The patient was diagnosed with colorectal cancer seven years earlier and had received chemoradiation, surgery, and multiple chemotherapies before she was started on regorafenib because of progressive pulmonary metastases. Computed tomography scans demonstrated cavitation of former nodular bilateral pulmonary metastases. After drainage and resolution of the right-sided pneumothorax, the patient returned eleven days later with recurrent symptoms caused by left-sided tension pneumothorax. Video-assisted thoracoscopy and bilateral pleurodeses were performed. Persistent air leaks with severe pain and pulmonary infiltrates led to the death of the patient. Conclusions: This case demonstrates the efficacy of oral antiangiogenetic therapy in advanced metastatic colorectal cancer. Nevertheless, it also depicts an important potential side effect by transforming multiple solid lung metastases into cavitations which led to recurrent pneumothoraces. Special attention should be paid to this phenomenon as treatment of these complications can be challenging.Background: Colorectal cancer is one of the most common cancer types, frequently metastasizing into the lungs.
