目的探讨肾嫌色细胞癌的螺旋CT多期动态增强表现,以提高术前诊断的准确率。方法回顾性分析14例经病理证实的肾嫌色细胞癌的术前螺旋CT动态多期扫描资料,重点观察肿瘤密度是否均匀及其强化程度及强化模式。结果14例肾嫌色细胞癌均表现为境界清晰的肿物,其中8例(57.1%)呈均匀密度。多期动态增强扫描10例(71.4%)强化峰值出现在实质期,4例(28.6%)强化峰值出现在皮髓质期。除1例肿瘤在皮髓质期强化程度高于肾皮质外,其余13例肿瘤在各期强化程度均明显低于肾皮质,差异有显著性(P<0.05)。结论肾嫌色细胞癌螺旋CT动态多期增强扫描表现有一定的特征性,境界清晰、密度均匀及轻到中度强化为其特点,有助于将其与其他类型的肾细胞癌鉴别。

Objective To investgate the dynamic-enhanced features of chromophobe renal cell carcinoma of spiral CT scan, so as to improve their diagnostic accuracy preoperatively. Method The preoperative dynamic-enhanced spiral CT of 14 patients with pathologically proved chromophobe renal cell carcinoma was analyzed retrospectively. Focus on the homogeneity or not, the degree and pattern of enhancement of the tumor. Result All 14 cases of chromophobe renal cell carcinoma had a sharp margin, 8 cases (57. 1%) showed homogeneous. The enhanced peak of 10 cases (71. 4%) were showed in nephrographic phase,4 cases (28. 6%) in the corticomedullary phase. Compared to re-nal cortex, all tumors except one had a significantly lower degree of enhancement in all enhanced phases ( P<0. 05). Conclusion Chrmophobe renal cell carcinoma has some characteristic features on dynamic-enhanced spiral CT scan and its features include a sharp margin, homogeneity and mild to moderate enhancement, and can help ra-diologists make a accurate diagnosis and differentiate it from other types of renal cell carcinoma.
