Figure 1. Computed tomography (CT) images of an acquired cystic disease-associated renal cell carcinoma in the 66-year-old man in Case Report 1. The left renal parenchyma is markedly thin and the dilated pelvis and calyx are filled with masses (*) without obvious enhancement in either phase (A–D). For the region of interest of a part of the lesion, the CT value of each phase was measured. (A) Plane phase (30 Hounsfield units [HUs]). (B) Corticomedullary phase (41 HUs). (C) Nephrographic phase (55 HUs). (D) Early excretory phase (42 HUs). There was no obvious calcification in the mass.
