目的探讨基础超声联合超声造影腹膜后良恶性肿物的特征。方法回顾性分析2004年3月至2013年3月间中山大学附属第一医院超声科进行常规超声检查及超声造影的27例腹膜后肿瘤(良性9例,恶性18例)病人病例资料。总结病变的超声特征,包括大小、形态、回声均匀性、边界、血流以及超声造影特征包括增强形态、均匀性、增强后边界,比较良恶性病变有无差异。结果腹膜后良恶性病变的大小、形态、回声均匀性、边界及血流差异均无统计学意义(P>0.05)。增强形态(周边向中央增强和中央向周边增强)良恶性病变之间差异有统计学意义,良性病变中由周边向中央增强为88.9%,恶性病变中由中央向周边增强为55.6%,良恶性病变增强均匀性和增强后边界比较差异均无统计学意义(P>0.05)。结论超声造影可能有助于腹膜后肿瘤良恶性的鉴别诊断,须增加样本量进一步总结。
Objective To investigate the characteristics of benign and malignant retroperitoneal complexed by ultrasound and ultrasonography. Methods The data of 27 cases of retroperitoneal tumor (9 cases of benign and 18 cases of malignant) undergoing routine sonography and sonography were retrospectively analyzed from March 2004 to March 2013 in the First Affiliated Hospital of Sun Yat-sen University. Ultrasound features of the lesion were summarized, including size, shape, echo uniformity, borderline, blood flow, and contrast-enhanced ultrasound features including enhanced morphology, uniformity, enhanced posterior border, and benign and malignant lesions. Results There was no significant difference in the size, shape, echo homogeneity, border and blood flow between the retroperitoneal benign and malignant lesions (P> 0.05). There was significant difference between benign and malignant lesions in benign and malignant lesions (88.9% in benign lesions, 55.6% in malignant lesions from the center to the periphery), benign and malignant lesions There was no significant difference between the enhancement of lesion and the enhanced border (P> 0.05). Conclusion Contrast-enhanced ultrasound may be useful for the differential diagnosis of benign and malignant retroperitoneal tumors, and the number of samples should be further summarized.
