【摘要】 目的 提高对肾细胞癌的CT诊断和病理认识。方法 回顾性分析24例肾细胞癌CT表现对照病理结果。结果16例为透明细胞癌,血供丰富,皮髓质期增强较明显,增强度>85Hu。3例乳头型肾细胞癌血供不丰富,皮髓质期无明显增强,增强度<80Hu。91.6％病例有皮髓质分界消失征象。54％肾癌生长以膨胀为主有假包膜征;70.8％以浸润生长为主有边缘棘状突及分叶征象。结论 于皮髓质期认识皮髓质分界消失征对肾细胞癌的诊断有重要价值,假包膜,棘状突,分叶征象对肾细胞癌诊断有一定的特异性。肾细胞癌的增强度对其亚型鉴别诊断有一定价值。更多还原

【Abstract】 Objective To improve CT diagnosis and pathologic knowledge of renal cell Carcinoma. Methods The CT data of 24 cases of renal cell carcinoma proved by pathology were retrospectively analyzed and correlated with pathologic findings. Results During the corti comedullary phase, 16 cases of clear cell carcinoma with rich blood vessel showed enhancement of CT image. While 3 cases papillary renal carcinoma with poor blood vessel didn’t show enhancement. Furthermore, the corticomedullary differentiation disappeared in 91.6% cases. In 54% cases, the foci growing dominantly in an expensive way were characterized with false capsule. In 70.8% cases, the foci growing dominantly in an infiltrative way were characterized with spur-like projections and tabulation. Conclusion The disappearance of the corti-comedullary differentiation during the cortex period is considered very important value for the diagnosis of renal neoplam. False capsule; spur-like projections and lobulation provide special distinction in CT diagnosis of renal cell carcinoma. Degree of enhancement is the most valuable parameter.更多还原
