摘要 患者,男性,48岁,因无明显诱因出现左侧腰痛,呈现间断性隐痛1周,当地医院CT提示左肾占位,于2020年11月以左肾肿瘤收入哈尔滨医科大学附属第一医院。实验室检查:血肌酐103.6μmol/L;纤维蛋白原定量5.35 g/L。增强CT示:左肾偏后部可见肿块影,其内见小低密度影,增强扫描见动脉期轻度强化,实质期及排泄期密度减低(图1)。提示:左肾占位,考虑肾癌可能性大。灰阶超声示:左肾中上部背侧可见大小5.9 cm×5.6 cm的高回声结节,边界尚清晰,轮廓规整,内部回声不均匀(图2);彩色多普勒血流显像(color Doppler flow imaging,CDFI)示:其内可见粗大条样血流信号,收缩期血流速度37 cm/s,舒张期血流速度15.9 cm/s(图3)。超声提示:左肾实性占位。
