| 摘 要： | 目的：腹膜后神经细胞源性肿瘤的组织来源多样，病理结构复杂，通过分析其超声声图像表现，探讨肿瘤良恶性的鉴别及提高超声定性诊断水平。方法：回顾性分析经手术病理证实的腹膜后神经细胞源性肿瘤25例，分析其超声声像图表现。结果：腹膜后神经细胞源性肿瘤多位于肾周、脊柱旁及肾上腺区；体积多较大；以低回声为主，可有囊性变及钙化且各具特点；边界清晰度与形态规整度良性肿瘤与恶性肿瘤组无明显差别（P>0.05）；血流丰富程度良恶性组无明显差别（P>0.05）；恶性肿瘤组的平均长径明显大于良性肿瘤组（P<0.025，a=0.05），具有显著差异；成神经细胞瘤以内部密集细小钙化为特点，而嗜铬细胞瘤则表现为血供较丰富伴散在小液性区。结论：腹膜后神经细胞源性肿瘤超声表现缺乏特异性，定性准确率较低；仅根据肿瘤形态、边界及血流显像情况判断其良恶性不可靠。

| Abstract: | Objective：The pathohistology of retroperitoneal neurogenic tumor is multiplex,by the analysis of the tumor’s ultrasonography,we try to discriminate the benign tumor from the malignant tumor and evaluate the ultrasonographic imaging features of retroperitoneal neurogenic tumor.Methods：The ultrasonographic imaging features of 25 cases were analyzed and compared with the results of pathology.Results：The common sites of retroperitoneal neurogenic tumor included spinal roots and the area surrounding kidney and adrenal;The tumors were large,mainly hypoechoic.Thirteen cases were cystic,13 cases had calcification;No difference between the benign and malignant tumors on the shape and boundary（P0.05）;No difference between the benign and malignant tumors on the color Doppler flow imaging（CDFI）（P0.05）;The diameter of the malignant tu-mor was much larger than that of the benign tumor（P0.025,a=0.05）.Close and tiny calcification was the characteristic of the neuroblastoma,the CDFI of pheochromocytoma was plentiful,associated with dispersed small cysts and there were its charac-teristics.Conclusions：The ultrasonograhic features of retroperitoneal neurogenic tumor is not characteristic and ultrasonograhic accuracy was not high;It is not reliable to distinguish the benign and malignant tumors by the shape,boundary or CDFI only. |
