Figure 1

(a) Initial diagnostic CT scan shows an ileocecal mass of approx. 7 cm of diameter, with no clear radiologic signs of bowel distention or obstruction. (b) Initial PET/CT scan shows a 7 cm FDG-avid paramediastinal lesion in stretch contact with the aortic arch. (c) Initial PET/CT scan shows a metastatic lesion at the hepatic segment V. (d) Control PET/CT scan after 2 cycles of carboplatin/etoposide shows complete resolution of the hepatic lesions. (e) Control CT scan after 2 cycles of carboplatin/etoposide and 3 cycles of carboplatin/paclitaxel shows tumor progression (left image) of the paramediastinal mass, further compromising the aortic arch.
