| Abstract: | Objective: To study the CT features of renal cell carcinoma (RCC) and their pathologic basis. Materials and Methods: CT and pathologic findings were compared and analyzed in 32 patients with pathologically proved RCC. Results: (1) On CT scan, the tumor margin presented three patterns: clear margin and without lobulation (50%); clear margin and lobulated (28%); blur margin (22%). (2) Pathologically, the tumor margin could be classified into types: intact capsule (48%); incomplete capsule or serrated margin (33%); without capsule (19%). (3) On enhanced CT scan, the size of lesions with blur margin on plain scan was decreased in 7 cases. Conclusion: (1) CT can well demonstrate the tumor margin, and is well correlated with the pathologic findings. (2) CT pattern of RCC margin is very helpful in assessing the extent of tumor invasion and in grading the tumor cells. |
