薄壁空洞性病変を呈した大腸癌肺転移の1例  [in Japanese] A case report of lung metastasis from colon cancer presenting as a thin-walled cavity  [in Japanese]

A 37-year-old woman underwent rectal amputation for rectal cancer in November 2005 and adjuvant chemotherapy with uracil-tegafur and leucovorin for 6 months. In October 2007, thin-walled cavity lesions were found in the right S8 and left S1+2, respectively, and solid lesions were found in the left S6 and S8, respectively, on computed tomography (CT) of the chest. Therefore, video-assisted thoracoscopic (VATS) wedge resection was performed to make a definite diagnosis, and the pathological findings revealed a metastatic lung tumor from the rectal cancer. It is important to consider the possibility of metastatic lung tumors if the cavity lesions are enlarged, exist in multiple regions, or exist together with nodular lesions in cases where thin-walled cavity-forming lung nodules develop in patients with a history of malignancy.
