Abstract Objective: To evaluate the CT appearances of renal chromophobe cell carcinoma(RCCC) and technique of CT. Methods: The CT features, clinical and pathological data of 4 cases of RCCC were analyzed retrospectively. Results: The RCCC showed solitary mass on CT scan, the size ranged from 3.5～9.0cm, with mean size of 5.43cm. The center of masses located in the renal medullary and expanded to cortex. Among the four cases of pre-enhanced CT images in three cases the mass density were homogeneous, one case had scattered spot calcification. On enhanced images, the mass of three cases showed enhancement from slight to moderate and the density lower than the renal parenchyma, and one case with patchy low density in the mass. Conclusions: CT scan plays an important role in RCCC examination and has some peculiar manifestation. It is a good and reliable method for pre-operation diagnosis of RCCC.
