A 36-year-old woman underwent sigmoidectomy with D3 lymphadenectomy and partial hepatectomy of the lateral and S4 segment on June 1999 under a diagnosis of sigmoid colon cancer with liver metastasis in the lateral and S4 segment. Histological diagnosis of the resected specimen was well-differentiated adenocarcinoma. She underwent postoperative adjuvant chemotherapy with arterial infusion of 5-FU using transarterial reserver and oral administration of 5'-DFUR. After the first treatment, she underwent 3 partial liver resections and radio-frequency-ablation (RFA) due to hepatic cancer recurrence over the next 18 months. Chest x-ray showed a lung tumor with cavitation in the middle left lung field 42 months after initial treatment. We suspected metastasis to the lung or pulmonary aspergilloma. Transbronchial lung biopsy failed to yield a definitive diagnosis, so we partially resected the lung. Pathological findings for the frozen section showed metastatic lung tumor from sigmoid colon cancer. Metastatic lung tumor rarely forms a cavity.
