原发性腹膜后肿瘤的CT诊断

CT diagnosis of primary retroperitoneal neoplasms

目的 探讨CT对原发性腹膜后肿瘤的诊断价值。方法 回顾性分析 18例经手术病理证实的原发性腹膜后肿瘤的CT表现。结果 CT对肿瘤定位诊断的准确率为 83.3% ,对良恶性判断的准确率为 77.8% ,术前病理组织类型判断准确率为 2 7.8%。结论 CT对原发性腹膜后肿瘤定位诊断可靠 ,对良恶性预测具有帮助 ,对病理类型估计能提供线索 ,有助于鉴别诊断。

Objectiv To investigate the value of CT in the diagnosis of primary retroperitoneal neoplasms(PRN). Materials and Methods CT findings in 18 cases with pathologically proved PRN were retrospectively analyzed Result The correct rate of CT localization was 83.3%(15/18).The accurate rate of CT in the prediction of benignancy or malignance was 77.8%(14/18). Conclusions CT was reliable for localization of PRN and useful for the prediction of their malignancy or benignancy, provided diagnostic clue for histologic evaluation of PRN and was helpful in differential diagnosis.
