C and D Massive pleural and peritoneal effusion, respectively (red arrows), and the incrassated subcutaneous tissue (blue arrows) of the right chest wall on CT images. E Increased uptake of ⁶⁸Ga-NEB in femur (thin, curved arrow), pleural effusion (thick, straight arrow) and skin (thin, straight arrow) on ⁶⁸Ga-NEB-PET/CT.
