Fig. 1From: Next-generation sequencing facilitates differentiating between multiple primary lung cancer and intrapulmonary metastasis: a case seriesComputed tomography (CT) scans showing pulmonary nodules detected in the cases presented in this series. a. In Case 1, two nodules of similar sizes (arrows) were observed in the two lobes of the left lung; b. A large number of small nodules were found in both lungs in Case 2. Shown here are two of the largest lesions; c. Transverse and frontal views of a nodule in the right upper lobe in Case 3. More miliary micronodules, although not readily discernable in CT scans, were discovered during surgical removal of this noduleBack to article page
