Comparative Study of CT Findings and Operation Pathology of Papillary Renal Cell Carcinoma

Objective: CT image analysis of papillary renal cell carcinoma, and explore the specific CT findings. Methods: Retrospective analysis of 10 cases, papillary renal cell carcinoma confirmed by operation and CT data. Results: All the cases were solitary mass, located in right kidney in 7 cases, in the left kidney in 3 cases, CT scan, tumors were round or oval, clear edge or less clear. Lesion diameter was 1.0~4.5 cm, average 2.5 cm. The tumor hours (≤ 3 cm) density is uniform, no cystic degeneration and necrosis; tumor is large (≥ 3 cm) often appear necrosis, cystic change. Tumor enhancement degree is low, the three stage is progressive mild enhancement, especially the excretory phase density is slightly reduced. Conclusion: Compared with other subtypes of renal cell carcinoma, CT manifestations of papillary renal cell carcinoma has certain features, mostly progressive enhancement, the diagnosis can provide the basis for the selection of operation.
