摘　　要：目的探讨腹膜后原发肿瘤的影像学特征与病理学的相关性。方法选择经手术病理证实的腹膜后原发肿瘤患者122例,术中病理诊断为良性肿瘤42例(良性组)和恶性肿瘤80例(恶性组),所有患者均给予CT平扫+增强扫描,部分行三维后处理,记录影像学特征,判断诊断效果。结果恶性组与良性组的CT图像质量优良率分别为97.5%和97.6%,对比差异无统计学意义。恶性组的病灶最大径、病灶密度及强化特征、腹膜后器官向前移位、脂肪间隙、界限不清等与良性组对比差异有统计学意义。恶性组平扫期、动脉期、门脉期的CT相对值均显著高于良性组。CT判断恶性肿瘤79例,良性肿瘤43例,并以其CT征象可对病灶术前准确达到病理性诊断,对腹膜后原发肿瘤的诊断敏感性与特异性分别为98.8%和100.0%。结论CT在腹膜后原发肿瘤中的应用能明确反映肿瘤与血管的空间关系,CT因为不同肿瘤组织密度不同,强化方式不同,有良好的影像学特征,与肿瘤的病理状况有很好的相关性。Objective To investigate the correlation between imaging features and pathology of primary retroperitoneal tumors.Methods 122 patients with primary retroperitoneal tumors confirmed by surgery and pathology were selected that included 42 patients of benign tumors(benign group)and 80 patients of malignant tumors(malignant group).All patients were given CT scans and enhanced scan,three-dimensional post-processing,recorded imaging features,and judging the diagnostic effect.Results The quality of CT images in the malignant group and the benign group were 97.5%and 97.6%,respectively,and the difference were not statistically significant.There were significant differences in the maximum diameter of the lesion,the forward displacement of the retroperitoneal organs,the fat gap,and the unclear boundaries compared between the 2 groups.The relative values of CT in the plain,arterial and portal phases of the malignant group were significantly higher than those of the benign group.The CT diagnosed 79 patients of malignant tumors and 43 patients of benign tumors.The diagnostic sensitivity and specificity of primary retroperitoneal tumors were 98.8%and 100.0%,respectively.Conclusion The application of CT in the retroperitoneal primary tumor can clearly reflect the spatial relationship between tumor and blood vessel.It has good imaging features and has a good correlation with the pathological condition of the tumor.
