[Solitary Pulmonary Metastasis from Carcinoma of the Ampulla of Vater after Pancreatoduodenectomy;Report of a Case].

A 74-year-old woman had underwent pancreatoduodenectomy for a carcinoma of the ampulla of Vater. After 3 years of the operation, chest computed tomography (CT) scan showed a solitary nodule in the right posterior segment (S2). Under the diagnosis of solitary pulmonary metastasis, we performed wedge resection for the right S2 lesion under video-assisted thoracic surgery (VATS). Pathological diagnosis was the metastasis of carcinoma of the ampulla of Vater. One year later, chest CT scan showed another solitary lesion in right superior segment (S6). Wedge resection was performed again for the right S6 nodule, which was also diagnosed as a metastasis.
