Fig. 1From: Long-term survival with repeat resection for lung oligometastasis from pancreatic ductal adenocarcinoma: a case reportImaging studies of the first pulmonary metastasis. Chest CT (53 months after curative resection of the primary pancreatic tumor) shows a tiny nodule at the lower lobe of the left lung (a). Follow-up CT (70 months after curative resection of the primary pancreatic tumor) shows that this nodule has enlarged to 2 cm in size with spiculation (b). It is difficult to determine whether this nodule is a primary or metastatic tumor on imagingBack to article page
