摘　　要：目的探讨肾嫌色细胞癌的多排螺旋CT影像表现,提高对肾嫌色细胞癌的影像诊断能力。方法回顾性分析2015年1月至2023年9月8例经手术病理确诊的肾嫌色细胞癌患者的临床及影像资料,总结其影像学表现。结果8例患者中男2例,女6例,年龄(46±4.7)岁。左右肾各4例。影像学表现:5例呈类圆形,形态规则,3例形态不规则;6例为外生型,2例为内生型;5例CT平扫密度均匀,其中4例等密度,1例稍低密度,均未见坏死、钙化、出血,3例混杂密度伴坏死、钙化;增强扫描6例不均匀强化,2例均匀强化;1例轻度强化,3例中度强化,4例明显强化,各期强化程度均低于肾皮质;2例强化峰值在动脉期,5例在门脉期,1例在静脉期;6例患者病灶内多发血管影,1例可见中央瘢痕延迟强化,1例可见分隔样强化;2例肿瘤可见包膜。结论肾嫌色细胞癌CT平扫多表现为等、稍低密度肿块影,可合并坏死、钙化,增强扫描强化方式多样,各期强化均低于正常肾皮质,呈相对乏血供肿瘤,瘤内可见血管样强化及中央瘢痕延迟强化。Objective To investigate the multi-detector spiral computed tomography findings of chromophobe renal cell carcinoma and to improve the imaging diagnostic ability of chromophobe renal cell carcinoma.Methods The clinical and imaging data of 8 patients with chromophobe renal cell carcinoma confirmed by surgical pathology from January 2015 to September 2023 were retrospectively analyzed,and the imaging findings were summarized.Results Among the 8 patients,6 were females and 2 were males,with an average age of(46±4.7)years.4 cases were located in the left kidney,and 4 in the right kidney,the imaging findings were as followed:5 were circular and regular,3 were irregular.6 were exogenous and 2 were endogenous.CT plain scan density was uniform in 5 cases,including 4 cases with isodensity and 1 case with slightly low density,no necrosis,calcification or bleeding was observed.3 cases showed mixed density with necrosis and calcification.The enhanced scan showed uneven enhancement in 6 cases and uniform enhancement in 2 cases,1 case showed mild enhancement,3 cases showed moderate enhancement,and 4 cases showed obvious enhancement,and the enhancement degree of each stage was lower than that of renal cortex.The peak value of enhancement occurred in arterial phase in 2 cases,portal phase in 5 cases and venous phase in 1 case.In 6 patients,there were multiple vascular shadows in the lesion,with delayed enhancement of central scar in 1 case and septal enhancement in 1 case.Capsule was seen in 2 cases.Conclusion Chromophobe cell carcinoma usually shows equal or slightly low density mass on plain CT scan,which may be combined with necrosis and calcification.The enhancement methods are various,and the enhancement at each stage is lower than that of normal renal cortex,showing relatively deficient blood supply tumor,vascular enhancement and delayed enhancement of central scar are seen in the tumor.
