Figure 1. A 40-year-old female had two solid opacities with the diameter of 3 mm and 5 mm in the right middle lobe, respectively; the preoperative imaging diagnoses were considered to be indeterminate.

The two patients then received the right middle lobe wedge resection, and the immediate frozen-resection histopathological results came out to be two atypical adenocarcinomas. There was no additional lobectomy performed. (A) Chest transvers-resection enhanced CT scan shows: two solid lesions in the right middle lobe (red arrows); (B) Two hookwires are placed through the lesions under CT guidance (red arrows); (C) The hookwires (red arrows) insert through the SPNs in pathologic specimen.
