摘要
目的探讨肾脏非透明细胞癌实性肿瘤的MSCT表现,旨在提高对其的诊断和鉴别诊断水平。方法对35例手术病理证实的肾脏非透明细胞癌实性肿瘤的CT表现进行回顾性分析,分析肿瘤部位、大小、形态边缘、有无包膜、出血、坏死、囊变、钙化、脂肪,平扫及增强扫描各期的CT值、强化方式,有无肾周侵犯及淋巴结转移等。结果乳头状肾细胞癌(n=4)、嫌色细胞肾癌(n=13)、血管平滑肌脂肪瘤(n=12)、嗜酸性细胞腺瘤(n=6)瘤内坏死分别出现3例、4例、3例、0例;出血分别为1例、3例、2例、0例;钙化分别为0例、3例、1例、0例;出现包膜者分别为2例、6例、0例、2例;杯口征分别为3例、6例、8例、1例;中央疤痕分别为0例、2例、1例、2例;瘤内血管分别为1例、9例、9例、2例;瘤周血管扩张1例、4例、3例、2例;增强后,轻中度强化者分别为3例、4例、2例、1例;明显强化者分别为1例、9例、10例、5例;辐轮状强化分别为1例、1例、0例、0例;节段性增强反转分别为1例、1例、1例、0例。结论乳头状肾细胞癌、嫌色细胞肾癌、血管平滑肌脂肪瘤、嗜酸性细胞腺瘤具有一定的影像学特征,掌握其特征性CT表现有助于与肾透明细胞癌的鉴别。
Objective To investigate the CT findings of solid tumors of renal non-clear cell carcinoma so as to improve the level of diagnosis and differential diagnosis of these tumors.Methods The CT findings of 35 patients renal solid tumors of non-clear cell carcinoma with surgically and pathologically proved were analyzed retrospectively.Results The CT fingings of papillary renal cell carcinoma(n=4),chromophobe cell renal carcinoma(n=13),renal angiomyolipoma(n=12)and oncocytoma(n=6)are as follows:tumor necrosis in 3 cases,4 cases,3 cases and 0 case,respectively,hemorrhage in 1 case,3 cases,2 cases and 0 case,respectively,calcification in 0 case,3 cases,1 case and 0 case,respectively;tumor capsule in 2 cases,6 cases,0 case and 2 cases,respectively;cup sign in 3 cases,6 cases,8 cases and 1 case,respectively,central scar in 0 case,2 cases,1 case and 2 cases,respectively,intra-tumoral blood vessels in 1 case,9 cases,9 cases and 2 cases,respectively,peripheral vascular dilatation in 1 case,4 cases,3 cases and 2 cases,respectively;mild and moderate enhancement in 3 cases,4 cases,2 cases and 1 case,respectively;marked enhancement in 1 case,9 cases,10 cases and 5 cases,respectively,spoke-wheel-like enhancement in 1 case,1 case,0 case and 0 case,respectively,segmental enhancement inversion in 1 case,1 case,1 case and 0 case,respectively.Conclusion The CT findings of renal solid tumors of non-clear cell carcinoma has some characteristics and is helpful in the diagnosis and differential diagnosis.
