原发性腹膜后肿瘤的CT诊断价值(附27例分析)

CT Diagnosis of Primary Retroperitoneal Neoplasms(Analysis of 27 Cases)

目的探讨原发性腹膜后肿瘤的CT表现。方法对27例穿刺活检和手术后病理证实的原发性腹膜后肿瘤的CT表现进行分析。结果对肿瘤的位置、大小、形态、密度、成份、边缘、与周围邻近组织的关系及增强扫描后CT的影像学资料进行分析,CT显示原发性腹膜后肿瘤的敏感性达100%,定位正确率为77.8%(21/27),良恶性定性诊断率为66.7%(18/27)。结论CT对原发性腹膜后肿瘤的定位及良恶性的判断有较高价值。

Objective To investigate CT features of primary retroperitoneal neoplasms（PRN）. Methods CT findings of 27 cases with pathologically-proved PRN were retrospectively analyzed. Results The presence, size, extent and composition of the tumor and also their effects on adjacent structures and the CT appearances of PRN were analyzed. The sensitivity of CT scan in detecting PRN was 100% , while the accuracy in localization of the lesions and quality were 77.8% and 66.7%. Conclusion CT has the high diagnosis value for the localization of PRN and the diagnosis of their malignancy benignancy.
