摘要
目的探讨乳头状肾细胞癌(papillary renal cell carcinoma,PRCC)的CT表现与病理特征之间的联系。方法搜集我院2009年-2012年经手术病理证实的12例乳头状肾细胞癌病例,分析其CT表现及相关临床资料。结果 12例中右肾7例、左肾5例,病灶直径2.8～11.2cm,平均5.2cm。10例边界清晰、2例边界不清,3例可见分叶。9例出现不同程度囊变,4例可见不规则钙化,2例瘤内可见出血,2例并发肾结石。平扫病灶CT值10～35HU,增强扫描肾皮质期CT值40～70HU,皮髓质期CT值45～80HU,延迟期CT值30～70HU,排泄期2例可见肾盂内出现充盈缺损。结论乳头状肾细胞癌的CT表现具有一定特征,通过CT增强四期扫描,可比较准确的对其进行术前诊断,为肿瘤分期的重要参考,也为确定手术方案提供帮助。
Objective To evaluate the relationship between CT manifestations of the papil- lary renal cell carcinoma（PRCC） and it＇s pathologic features. Methods 12 cases of papillary renal cell carcinoma which confirmed by surgery and pathology were reviewed. Results Of all the 12 cases, lesions of 7 cases in the right side and 5 cases in the lefi kidney. The mean diameter of tumors was range from 2.8 to 11.2 cm with an average of 5.2 cm. The boundary of lesions in 10 cases were clear, others are unclearly. 3 lesions were lobulated, 9 cases with cystic degeneration, 4 cases with calcification, 2 cases with hemorrhage, and 2 cases with kidney stones. CT values of plain scan ,cortex phase, cortico-medullary phase and delayed phase were 10-35 HU, 40-70 HU, 45-80 HU and 30 - 70 HU, respectively. There can be seen filling defect in pelvis in excretory phase. Conclusion PRCC has a certain CT imaging features. We can make a comparative accurate diagnosis before the operation by CT en- hancement scan of 4 phases. It can not only provide an important reference to tumor staging, but also help to make a right operation plan.
