肌内黏液瘤超声图像特征及其临床辅助诊断价值

Characteristics of ultrasound imaging of intramuscular myxoma and its clinical value in auxiliary diagnosis

目的分析肌内黏液瘤(IM)的超声图像特征,为临床提供辅助诊断肌内黏液瘤的依据。方法对12例确诊为肌内黏液瘤患者二维及彩色多普勒超声表现特征做回顾性分析。所有患者术前均曾接受过超声检查,分析超声影像资料,总结临床超声图像特点。结果患者超声图像后方回声增强,内部为不均匀低回声,其中9例可见片状无回声区;12例病灶周边出现环状较高回声("亮环征"),均不完整;11例在长轴切面团块的两极(上极、下极)周围出现类似三角形强回声区("亮帽征")。彩色多普勒显示:9例IM病灶内无血流;3例部分区域内见点线状血流信号。结论 IM的超声表现具有一定特异性,熟悉IM的超声表现,有助于提高诊断准确率,为临床提供更多的信息。

Objective To analyze the ultrasonographic features of intramuscular myxoma and provide the basis for the clinical diagnosis of intramuscular myxoma. Methods The characteristics of two-dimensional and color Doppler ultrasonography in 12 patients with intramuscular myxoma were analyzed retrospectively. All patients were examined by ultrasonography before operation, and the imaging data was analyzed. Results The posterior echo of ultrasonic images of the patients was enhanced, and the internal echo was uneven and low. In 12 cases, the circumferential high echo（＂bright ring sign＂） was incomplete. The two poles（upper and lower poles） of the tangent mass in 11 cases were similar to the strong triangle echo region （＂bright cap sign＂）. Color Doppler shoued that： 9 cases without blood flow; For 3 cases, the blood flow signals were seen in some areas. Conclusion The sonographic features of IM are specific, and it is helpful to improve the diagnostic accuracy and provide more information for the clinic by understanding the ultrasonic manifestations of IM.
