During the hospitalization, a PET was performed showing increased activity in the already known lung metastasis and a new image with also increased activity that extended from the thoracic inlet to the anterior mediastinum (Figure 1(a)). The PET was compared with the previous CT (Figures 1(b) and 1(c)) by the radiologist, who reports an intravascular metastasis of 23 x 31 x 45 cm.
