A and B, 2D low-dose unenhanced prone (A) and post-contrast supine (B) CTC images show an irregular 1 cm soft tissue nodule (arrows) adjacent to the colonic anastomosis (arrowheads). Note the peripheral enhancement of the nodule on the contrast-enhanced view, as well as collapse of the anastomosis. The anastomosis was deemed normal at OC (not shown).

C, Fused image from PET/CT obtained after the CT/CTC study shows that the lesion is hypermetabolic, which proved to be local recurrence.
