摘　　要：目的探讨原发性腹膜后副神经节瘤的CT表现特征，提高对该病的诊断水平。方法对13例原发性腹膜后副神经节瘤患者进行回顾性分析，重点观察肿瘤的位置、大小、形态、密度及强化特点。结果13例患者均为原发病灶，呈类圆形、类椭圆形及不规则形状，其中有3例肿瘤为恶性，包膜不完整，术后复发伴其他脏器转移，余10例均为良性，包膜完整，密度均不均匀；13例患者中有5例可见钙化，5例见斑片状坏死，3例见条带状钙化及斑片状坏死；13例患者增强扫描均呈中等度不均匀强化，其中3例瘤体内见粗大血管影，该3例患者中1例为良性。13例患者中以体检发现腹部肿块者10例；以高血压症状就诊者3例，其中1例为恶性副神经节瘤。结论原发性腹膜后副神经节瘤的CT表现具有一定的特异性，结合临床症状有助于术前诊断，对临床有很大的指导意义。Objective To investigate the CT features of primary retroperitoneal paragangliomas and improve the diagnosis ability about it.Methods We examined 13 patiens with SIEMENS sensation 64 CT, analysed the characteristics of primary retroperitoneal paragangliomas retrospectively, and observed the position,size,shape,density and strengthening characteristics of primary retroperitoneal paragangliomas.Results All of the 13 patients were all primary lesions.3 cases of the 13 patients were malignant,the membrane of them were not intact,with recurrence and metastasis after surgery.The other 10 patients were benign,the membrane of them were intact,the density were uneven,5 cases of the 13 patients could be seen with calcification,5 cases could be seen with flake of necrosis,3 cases could be seen with flake of necrosis and ribbon of calcification.Medium inhomogeneous enhancement showed on CT imaging,crude vascular were shown in 3 cases of the 13 patients,one case of them was benign.3 cases of the 13 patients had high blood pressure,that only one of them was malignant. Conclusion Primary retroperitoneal paraganglioma has specificity of CT findings,clinical symptoms will help the preoperative diagnosis,and has a great help for clinical.
