原发性腹膜后肿瘤及肿瘤样病变的影像诊断

The imaging diagnosis of primary retroperitoneal tumor and tumor-like lesion

目的探讨各种影像学检查对原发性腹膜后肿瘤及肿瘤样病变的诊断价值。方法对13例经手术病理证实的腹膜后肿瘤的X线、CT、MRI及超声表现特点进行分析。结果超声、CT及MRI的定位诊断准确率分别为75 %、90 %和10 0 %。良性与恶性肿瘤的大小无显著差异。CT与MRI能较直观显示肿瘤的大小、形态、成分及与周围组织的情况。结论超声、CT、MRI均具较高的定位诊断价值。CT及MRI可较好地显示肿瘤的境界及质地,对腹膜后肿瘤及肿瘤样病变的定性诊断有重要的价值。

Objective:To discuss imaging diagnostic value of primary peritoneum tumor and tumor-like lesion.Methods:To analyse 13 cases characteristic imagings of X-ray and CT and MRI and Uitrasound of primary peritoneum tumor and tumor-like lesions which have been confirmed by pathology after the surgical operation.Results:The accurate location rate of ultrasound and CT and MRI is 75% and 90% and 100%,the size of lesions has no difference between benign and malignant tumor.The CT and MRI can display the size,shape, ingredient and the surrounding tissue of tumors.Conclusion:The ultrasound, CT, MRI has the higher location value.The CT and MRI can manifest the qualities and boundary of tumors,and have important diagnostic value to primary peritoneum tumor and tumor-like lesions.
