폐전이에서 공동성 폐병변이 관찰되는 경우가 흔하지 않으며, 다른 양성 폐병변과 감별이 필요하다. 저자들은 다발성 공동성 폐병변을 주소로 내원한 환자에서 굴곡성 기관지내시경 검사를 통한 조직검사상 전이성 폐암을 진단하였고 원발성 병변인 담관암을 진단하여 전신적인 항암약물을 시행한 경험이 있어 이에 보고하는 바이다.
Because a cavitary pulmonary metastasis is rare, it may not be readily identified. However, various types of cancers can metastasize to the lung in the form of cavities. We report a case of a multiple cavitary metastases to the lung from a cholangiocarcinoma in a 60-year-old man. He complained of generalized weakness and a poor oral intake for 2 months. The plain chest radiography and the chest computed tomography showed multiple small thick-walled cavities and nodules the both lungs. A bronchoscopic examination revealed a focal irregularly elevated surface of the mucosa at the orifice of the superior segment of the right lower lobe and the biopsy demonstrated an infiltrative metastatic adenocarcinoma. The abdomen-pelvis computed tomography showed an ill-marginated and irregularly low-dense area in the right lobe of the liver and a diffuse dilatation of the peripheral intrahepatic bile ducts. The esophagogastroscopy and colonoscopy showed no abnormal findings. It was concluded that the cholangiocarcinoma of the liver metastasized to the lung in the form of cavities. Thereafter, the patient underwent six cycles of the systemic chemotherapy with gemcitabine and cisplatin, and the follow-up imaging studies showed a partial response.
