摘　　要：目的：了解64层螺旋CT三维成像技术在腹膜后巨大肿瘤诊治中的应用价值。方法：回顾分析2005年1月至2010年12月诊治的18例腹膜后巨大肿瘤的临床资料。结果：年龄23～64岁,男13例,女5例,术前主要诊断方法有常规CT、MRI、64层螺旋CT三维成像等,评估肿瘤的数目、大小、相邻关系,并与术中情况比较,其中CT三维成像显示均与术中发现一致,18例均成功实施肿瘤切除术,肿瘤（6～18）cm×（7～12）cm×（6～10）cm,位于左侧腹膜后10例,右侧6例,双侧2例,术后病理诊断肾上腺癌8例,肾上腺嗜铬细胞瘤5例（其中双侧2例）,腹膜后横纹肌肉瘤1例,畸胎瘤1例,肾上腺腺瘤3例。结论：对于腹膜后巨大肿瘤,64层螺旋CT三维成像能提供更准确的解剖细节,有助于手术方案的设计和成功实施,提高手术安全性。Objective： To evaluate the diagnostic value of 64-slices 3D-spiral CT on large retroperitoneal tumor. Methods： The data of 18 patients with large retroperitoneal tumor were retrospectively analyzed. Results：13 cases were male and 5 were female, age ranged from 23 to 64 years. The preoperative diagnosis depended mainly on the results of routine CT, MRI and 64-slices 3D-spiral CT. The results of imagings were compared with that of surgical and pathological findings. These cases included adrenal carcinoma（8 cases）, adrenal phaeoc-hromocytoma（5 cases）, retroperitoneal rhabdomyosarcoma（1 case）, teratoma（1 case） and adrenal adenoma（3cases）. The results of 64-slices 3D-spiral CT were identical with the operative findings. Conclusion： 3D-spiral CT reconstruction of large retroperitoneal tumor has the advantage of high resolution,which provides more accurate anatomic details for the design of surgical procedures.
