摘　　要：目的总结原发性腹膜后肿瘤的CT表现特征,旨在提高对此类少见肿瘤的认识。方法回顾原发性腹膜后肿瘤24例,与病理对照,分析各类肿瘤的影像学特点。结果脂肪(肉)瘤8例,以脂肪性成分为主;纤维肉瘤2例,周围浸润明显;平滑肌肉瘤2例,呈多中心融合形;神经鞘瘤4例,好发脊柱旁,易囊变;节细胞神经瘤1例,密度低,特征性不明显;神经母细胞瘤1例,大片状钙化;副神经节瘤1例及化学感受器瘤2例,增强明显;异位嗜铬细胞瘤1例,增强明显有囊变;神经内分泌瘤1例,无特征;畸胎瘤1例,三胚层组织共存。结论CT对原发性腹膜后肿瘤定位准确。肿瘤CT表现多样化,仅部分肿瘤特征性明显。Objective To discuss the CT features of primary retroperitoneal tumor（PRT） ,so that to improve the knowledge of these diseases.Methods 24 cases with PRT confirmed by surgery and pathology were assessed retrospectively,and their CT manifestations were analyzed in comparison with pathology. Results All cases included：8 cases of liposarcoma with predominant fat components, 2 cases of fibrosarcoma with evident involvement of adjacent tissues,2 cases of leiomyosarcoma with multiple centers fused, 4 cases of schwannoma localized at paraspine and cystic generation commonly,1 case of ganglioma with hypodense parenchyma,1 case of neuroblastoma with large calcification, 1 case of paraganglioma and 2 cases of chemodectoma and enhanced obviously,1 case of pheochromocytoma enhanced evidently with cystic generation ,1 case of neuroendocrinoma without specific characteristic and 1 case of teratoma with 3 layers of embryo tissues. Conclusion CT acan is able to localize the primary retroperitoneal tumors accurately,but specific CT features only see in some cases.
