目的 :探讨研究体表软组织脂肪肉瘤超声图像特征 ,以提高超声诊断和鉴别准确性。方法 :对临床患者进行反复多次超声扫查以获取图像资料。结果 :1.超声显示包块一般较大。 2 .边界具有大多数恶性肿瘤的共同表现。 3.内部回声与肿块的大小和部位有密切关系 ,较小者内部回声较密集 ,以实性中等细小光点为主 ,镶嵌不规则的片状低弱回声 ,较大者出现范围较大的沼泽样低弱暗区。 4 .肿块后方声衰特征不明显。 5 .肿块质软有压缩性。 6 .肿块内血流信号极丰富呈低阻状频谱。结论 :超声图像表现有一定的特征 ,对脂肪肉瘤的诊断有一定指导价值 ,与临床诊断符合率为 71.4 3%。准确诊断必需结合病理检查 ,须与脂肪瘤、肢体血管瘤、软组织纤维肉瘤等鉴别
Objective: To explore the characteristics of ultrasound images of the surface soft tissue liposarcoma in order to improve the accuracy of ultrasound diagnosis and identification. Methods: Repeated multiple ultrasound scans were performed on clinical patients to obtain image data. Results: 1. Ultrasound shows that the mass is generally larger. 2. The boundary has the common appearance of most malignant tumors. 3. The internal echo is closely related to the size and location of the mass. The smaller ones are denser in internal echoes, mainly in solid medium and small light spots, with irregular patches of low-echo echoes and larger ones. Swamp like low and dark areas. 4. The characteristic of sound attenuation behind the mass is not obvious. 5. The mass is soft and compressible. 6. The blood flow signal in the mass is very rich and shows a low resistance spectrum. Conclusion: There are certain features in the ultrasound image, and it has certain guiding value for the diagnosis of liposarcoma. The coincidence rate with the clinical diagnosis is 71.4 3%. Accurate diagnosis must be combined with pathological examination, be identified with lipoma, limb hemangioma, soft tissue fibrosarcoma, etc.
