图1 左肾肿块常规超声及超声造影表现。图a为常规超声图像,图b为彩色多普勒血流成像,图c为超声造影图像:左肾下极肿块可见囊壁及多个增厚的分隔增强,其余部分无增强
图2 左肾肿块CT平扫+增强图像。左肾下极见不均匀等/稍低密度类圆形肿块影,边缘见少许断续线壳样钙化,增强扫描见壁结节强化(箭头示强化的壁结节)。图a为CT平扫图像;图b为增强动脉期图像;图c为增强静脉期图像
图3 未分类肾细胞癌术后病理及免疫组化图像。图a示镜下见肿瘤细胞呈巢状分布,大部分细胞胞浆透明,部分胞浆嗜伊红性、细颗粒状,部分可见细小核仁。部分区域呈实性排列,部分区域可见囊性出血、纤维分隔(HE×100)。图b示免疫组化标记PAX8(+);图c示免疫组化标记ksp-cad(+);图d示免疫组化标记TFE-3(-)
