目的:探讨腹膜后脂肪肉瘤超声声像图特点,评价超声成像在腹膜后脂肪肉瘤诊断方面的价值。方法:本组病例共10例,其中4例为术后复发。10例中,男性2例,女性8例,年龄在37岁～55岁之间,平均年龄47岁。所有病例均在手术前作超声检查,并与术中病理发现和病检结果对照分析。结果:10例患者二维超声与彩色多普勒显像表明肿块均来自腹膜后,定位诊断符合率100％,且表现为实质非均质性包块,5例肿块性质超声提示为脂肪肉瘤,4例考虑脂肪肉瘤术后复发,1例超声疑为胰头癌。结论:脂肪肉瘤的超声显像具有方便、无创、价格便宜、便于动态观察等优点,且定位准确,可以提供有关肿瘤形态、大小及内部结构特征等信息,对于临床治疗及早期诊断有重要意义。
Objective: To investigate the ultrasonographic features of retroperitoneal liposarcoma and to evaluate the value of ultrasonography in the diagnosis of retroperitoneal liposarcoma. Methods: A total of 10 cases in this group, of which 4 cases of postoperative recurrence. 10 cases, 2 males and 8 females, aged 37 to 55 years old, with an average age of 47 years. All cases were performed ultrasound before surgery, and pathological findings and pathological examination of intraoperative control analysis. Results: Two-dimensional ultrasonography and color Doppler imaging of 10 patients showed that the tumors were all from the retroperitoneum. The coincidence rate was 100%, and the masses showed substantial heterogeneity. The ultrasound findings of 5 masses showed liposarcoma, 4 cases considered recurrence of liposarcoma, 1 case of suspected pancreatic cancer. Conclusions: Ultrasound imaging of liposarcoma is convenient, noninvasive, inexpensive and easy to observe dynamically. The accurate location of the tumor can provide information about tumor morphology, size and internal structure, which is of great significance for clinical treatment and early diagnosis.
