The 18FDG PET scan after intervention (October 2017), revealed a residual tumor in the lymph nodes located in left retro-mandibular and latero-cervical areas (maximal SUV 3.9) and a nodule in the mesenteric adipose tissue in right hypogastrium (Figure 2A). The first 18FDG-PET/CT scan after 4 months of therapy revealed the persistence of lymph node disease (with increased maximal SUV to 4.4), while the mesenteric nodule was stable (Figure 2B). The mesenteric nodule was not modified (Figure 2C).
