An example of a renal cell cancer patient on sunitinib treatment in which the lung lesion (arrow) showed a decrease in attenuation at first evaluation. (A) At baseline, the tumour attenuation was 107 Hounsfield units (HUs) and the longest diameter 48 mm. (B) At first evaluation, the tumour attenuation was 65 HUs (−39%) and the longest diameter was 39 mm (−19%).
