摘要 目的探讨后肾腺瘤的计算机断层扫描(CT)诊断及病理特征。方法收集郑州大学第五附属医院收治的4例后肾腺瘤患者的临床、CT、病理检查结果等相关资料,进行回顾性分析,总结归纳其特点。结果4例后肾腺瘤患者中,男3例,女1例。肿瘤均位于右肾,呈类圆形,CT平扫呈稍高密度,内可见少量坏死,2例内有钙化,增强后1例呈明显延迟强化,2例呈轻度延迟强化,1例呈“快进快出”强化。病理检查示:肿瘤细胞呈管状或腺泡状排列,细胞异型性不明显;免疫组化示Vimentin阳性2例,CK阳性3例,肾母细胞瘤基因-1阳性2例,Ki-67均≤5%阳性。结论后肾腺瘤的CT表现有一定的特征性,有助于临床诊断,最终确诊有赖于术后的病理及免疫组化检查。
