摘　　要：目的分析并总结阴囊内脂肪肉瘤的超声图像特征,提高超声对其的诊断准确率。方法收集我院经手术病理确诊的5例阴囊内脂肪肉瘤患者,总结其临床及超声图像特征。结果5例患者的平均年龄为(63±18)岁;病变均位于左侧阴囊,肿瘤平均最大径为(11.9±2.8)cm。声像图表现为:2例高分化脂肪肉瘤表现为高回声,1例混合型脂肪肉瘤(包含高分化和黏液样成分)表现为高、低回声相间的混合回声,2例去分化脂肪肉瘤表现为低回声(其中1例伴低回声、无回声相间的混合回声);CDFI示瘤内未探及血流信号或仅探及点状血流信号。结论阴囊内脂肪肉瘤声像图表现多以实性为主,血流多不丰富,不同病理类型脂肪肉瘤的回声具有差异。Objective To analyze and summarize the ultrasonic image characteristics of intrascrotal liposarcoma,and to improve the accuracy of ultrasonic diagnosis for this disease.Methods Five patients diagnosed as intrascrotal liposarcoma in our hospital were collected,and the clinical and ultrasonic image characteristics were summarized.Results The average age of the 5 patients was(63±18)years.The lesions were located on the left scrotum,with an average maximum diameter of(11.9±2.8)cm.The sonographic appearances of the tumors varied:two cases of well-differentiated liposarcomas showed hyperechoic ultrasound patterns,one case of mixed-type liposarcoma(containing both well-differentiated and myxoid components)showed alternating hyperechoic and hypoechoic patterns,and the other two cases of dedifferentiated liposarcomas showed hypoechoic ultrasound patterns,with one of them presenting as a mixed echo pattern containing both hypoechoic and anechoic areas.CDFI showed that the intrascrotal liposarcomas generally demonstrated no blood flow or punctate blood flow signals.Conclusion Sonographic findings of intrascrotal liposarcoma are predominantly solid,with generally poor blood flow,and the echogenicity varies among different pathological types of liposarcoma.
