摘要
目的 分析并总结脂肪肉瘤的超声图像特征。方法 回顾性分析我院经手术病理证实的31例脂肪肉瘤患者的超声资料,分析不同病理亚型的脂肪肉瘤超声图像特征。结果 31例患者中,去分化脂肪肉瘤13例,高分化脂肪肉瘤10例,多形性脂肪肉瘤4例,黏液样脂肪肉瘤4例;肿瘤最大径为(16.97±9.70)cm,以等或高回声(61.3%,19/31)为主,且回声分布多不均匀(90.3%,28/31),CDFI多表现为乏血供,Adler血流分级以0、Ⅰ级为主(96.8%,30/31)。其中,高分化脂肪肉瘤以高回声为主(70.0%,7/10);去分化脂肪肉瘤边界多不清晰(92.3%,12/13),以低回声(46.2%,6/13)和高回声(30.8%,4/13)的双相模式为主;多形性脂肪肉瘤边界多清晰(3/4);黏液样脂肪肉瘤CDFI均表现为极度乏血供(4/4)。结论 脂肪肉瘤的超声表现具有一定的特征性,对临床辅助诊断该病能够提供一定的帮助。
Objective To analyze and summarize the ultrasonic features of liposarcoma.Methods The ultrasonic datas of 31 patients with surgical pathologically confirmed liposarcoma in our hospital were retrospectively analyzed,and the ultrasonographic features of different pathological subtypes of liposarcoma were analyzed.Results Among the 31 patients,there were 13 cases of dedifferentiated liposarcoma,10 cases of well-differentiated liposarcoma,4 cases of pleomorphic liposarcoma,and 4 cases of myxoid liposarcoma.The maximum diameter of the tumors was(16.97±9.70)cm.The lesions were predominantly iso-hyper-echoic(61.3%,19/31),with heterogeneous echo distribution(90.3%,28/31).CDFI mostly showed lack of blood supply,and Adler blood flow classification was mainly grade 0 and gradeⅠ(96.8%,30/31).Among them,well-differentiated liposarcoma was mainly hyperechoic(70.0%,7/10).Poorly defined boundaries of dedifferentiated liposarcoma were observed in 92.3%(12/13),and the lesions showed the biphasic pattern of hypoechoic in 46.2%(6/13)and hyperechoic in 30.8%(4/13).Pleomorphic liposarcoma was mostly characterized by a well-defined mass(3/4).The manifestations of CDFI in myxoid liposarcoma were extreme lack of blood supply(4/4).Conclusion The ultrasonic manifestations of liposarcoma have certain characteristics,which can provide some help for the clinical diagnosis of the disease.
