| Abstract: | Purpose: To report the CT and MRI manifestations of granular cell renal cell carcinoma. Materials and Methods: Eight cases of granular cell renal cell carcinoma proved by surgery and pathology were examined by means of CT and MRI. Their CT and MRI manifestations were retrospectively reviewed. And these manifestations were compared with that of 40 cases of clear cell renal cell carcinoma. Results: The masses were 2 cm to 5 cm in diameter. CT and MRI characteristic manifestations included: homogenous density or signal in non - enhancement scan, an intact capsule of mass, homogenous enhancement after administration of contrast media and were hypodensity or hypotension than renal cortex in corti-comedullary phase. Conclusion: The CT and MRI manifestations of granular cell renal cell carcinoma were difference with those of clear cell renal cell carcinoma and could be used for differentiation. |
