摘　　要：目的分析腹膜后节细胞神经瘤(GN)的CT影像特点,并结合病理回顾分析,以提高诊断准确性。方法回顾性分析经病理证实的16例腹膜后GN的CT影像表现。结果位于肾上腺11例,肾上腺外腹膜后5例。16例均境界清楚,4例形态不规则,12例形态规则,2例可见有伪足或呈嵌入式生长。密度均匀6例,不均匀10例。伴钙化4例,含脂肪1例。12例轻度不均匀延迟强化,4例中度及以上不均匀延迟强化。3例肿瘤内见穿行血管影,3例GN包绕周围大血管。结论腹膜后GN特征的CT表现有助于诊断。Objective To study CT and pathological features of ganglioneuroma （GN） in the retroperitoneal space to im- prove diagnostic accuracy. Methods Sixteen cases＇ CT manifestations of histopathologically confirmed GN were studied retro- spectively. Results GN located in the adrenal （11） and the extra-adrenal retroperitoneal space （5）. All of GN was well-de- fined. GN shaped as irregularity （4）, regularity （12）, and showed pseudopodium or a tendency of wedging into the space （2）. The density of GN was homogeneous （6） and heterogeneous （10）. Calcifications （4） and fatty component （1） were seen. GN showed mild （12） and moderate / marked （4） heterogeneous delayed enhancement after contrast administration. Vessels through the tumors were seen in three cases and three cases manifested surrounding the adjacent great blood vessels, Conclusion CT fea- tures of GN in retroperitoneal are helpful for GN diagnosis.
