目的：探讨腹膜后节细胞神经瘤（ GN）的影像表现，并分析其强化特征。方法分析经手术病理确诊的37例腹膜后GN的影像学特征，并与手术病理结果对照。37例全部接受CT平扫，其中22例接受CT增强扫描。结果37例腹膜后GN中，病灶位于右侧者23例，位于左侧者14例。所有病灶均边界清楚，圆形或类圆形19例，不规则形18例。 CT平扫26例34个病灶密度均匀，与囊性病变密度接近，11例17个密度不均，可见少许斑点状、小条状钙化灶；增强扫描动脉期病灶无明显强化，静脉期及延迟期可见渐进性强化。结论腹膜后GN具有一定的特征性影像学表现及强化特征，有助于其诊断和鉴别诊断。

Objective To investigate the retroperitoneal ganglioneuroma ( GN) imaging findings ,and analyze its enhanced features .Methods 37 patients with retroperitoneal GN confirmed by pathology were chosen as subjects , the imaging features were analyzed and were compared with the pathologic results .All 37 cases underwent CT scan ,22 patients underwent CT enhance scan .Results 37 cases of retroperitoneal GN ,the lesions were located in the right side in 23 cases,14 cases located on the left.All lesions were demarcated,round or oval in 19 cases,18 cases of irreg-ular shape.CT scan 26 cases of 34 lesions of uniform density ,and density close to cystic lesions ,11 cases of 17 une-ven density,showed a little patchy,small strips calcification.Enhanced arterial phase lesions no enhancement ,venous phase and delayed phase showed progressive enhancement .Conclusion Retroperitoneal GN has certain characteristic imaging findings and strengthen the characteristics contribute to its diagnosis and differential diagnosis .
