摘要 病人,女,32岁。体检发现左肾占位十余天于2020年6月10日入院。2020年6月13日CT检查提示:左肾占位,肾盂癌可能。2020年6月28日超声检查提示:左肾癌。无腰痛、血尿、发热等症状。体格检查未见明显异常。辅助检查:超声检查左肾内低回声团块,界线清晰,可见包膜,内可见细小无回声区,周边见彩色血流信号环绕。超声造影检查提示肿块内造影剂进入晚于肾皮质,呈低增强,强化后可见筛孔样改变,退出与肾皮质基本同步。CT检查提示:左肾中极见一软组织密度肿块影,边界尚清,密度均匀,增强扫描呈轻中度强化,肿块压迫肾盂肾盏(图1)。MRI检查:左肾髓质区见团片状异常信号影,界线清晰,T1WI呈等信号,T2WI呈等稍低信号,DWI呈高信号,增强扫描未见明显强化(图2)。于2020年7月10日行腹腔镜下左肾肿瘤切除术。
