摘　　要：目的探讨术前超声诊断侵袭性血管黏液瘤(AAM)的临床价值。方法回顾性分析10例经手术病理检查证实的AAM患者资料,观察AAM的临床特点及术前超声表现。结果 10例AAM患者病灶位于盆腔2例,外阴4例,会阴部延伸至盆腔2例,臀部延伸至盆腔2例。超声均表现为形态不规整的肿块;8例边界清,2例边界稍模糊;3例呈液性伴密集细小点状回声,2例呈不均匀中等回声,1例呈中、低混杂回声,4例呈不均匀低回声;CDFI显示3例未见血流信号,5例可见少量血流信号,2例可见丰富血流信号。术前超声对10例AAM均准确定位,但7例未能定性诊断,3例误诊。结论 AAM临床表现缺乏特征性,超声检查有助于明确肿瘤的位置、侵及范围,但定性诊断较为困难。Objective To explore the clinical value of preoperative ultrasound in diagnosis of aggressive angiomyxoma（AAM）.Methods Data of totally 10 patients with AAM confirmed by pathology were retrospectively analyzed.All the patients underwent ultrasound before surgery.Clinical and imaging features of AAM were studied.Results The lesions of AAM located in pelvis of 2cases and in vulva of 4cases.The lesions extend from perineum to pelvis were detected in 2cases.And the lesions extending from buttock subcutaneous to pelvis were detected in 2cases.The lesions in all of 10 cases were shown as irregular margins by ultrasonography,including well-demarcated lesions in 8cases and slightly ill-defined lesions in 2cases.There were distributed hyperechoic spots within nonechoic lesions in 3cases,inhomogeneous isoechogenicity lesions in 2cases,inhomogeneous mixed echogenicity（low-equal echo）lesion in 1case and inhomogeneous hypoechoic lesions in 4cases.No obvious blood flow signal was found in 3cases,while few of blood flow signals were observed in 5cases and abundant blood flow signals were observed in 2cases.The lesions of 10 AAM patients were located accurately by preoperative ultrasound.But the qualitative diagnosis were failed in 7cases and ultrasonic misdiagnosis occurred in another 3cases.Conclusion The clinical feature of AAM are no specific.Preoperative ultrasound is helpful to detect the location and extension of AAM lesions,but qualitative diagnosis is difficult.
