Abstract
Objective:To assess the value of CT in the diagnosis of papillary renal cell carcinoma(PRCC). Methods: Imaging findings of 17 patients with PRCC confirmed by surgery and pathology were reviewed retrospectively. Sixteen patients underwent spiral CT without and with contrast enhancement. Two patients underwent plain and dynamic enhanced magnetic resonance imaging (MRI) . Results: Tumors were located in the right kidney in 9 patients and in the left kidney in 8 patients. The mean diameter of tumors was 5. 6 cm(rangc 2. 0 -12. 4 cm). The shapes of tumor were round or oval in 13 patients and lobulatc in 4 patients. The margins of tumors were distinct in 13 cases and indistinct in 4 cases. The density of tissue at the tumor site was hctcrogcncously dense in 13 cases and homogeneously dense in 4 cases. CT values of the plain scans,corticomcdullary phase and ncphrographic phase were 17. 8-35. 5HU(mcan 26. 1HU),27. 3-57. 5HU(mcan 37. SHU) and 35. 0-71. 2HU(mcan 47. SHU) , respectively. The signal characteristics of MRI abnormalities both on TjWI and T2WI depended on the composition of PRCC. The patcrns of MRI dynamic enhancement were similar to those of CT. Conclusions: Dynamic contrast-enhanced CT and MRI can provide valuable information for the diagnosis and differential diagnosis of PRCC.关键词
