| 目的 通过分析和总结Morel-Lavallée损伤（MLL）的声像图特征，以期提高该病的超声诊断准确率。方法 回顾性分析2018年3月～2021年5月经证实的22例Morel-Lavallée损伤的临床及超声资料。彩色多普勒超声重点评估病灶位置、形态、大小、内部回声特征、有无包膜、内部有无分隔及血流信号、包膜有无血流等。结果 22例均有明确的外伤史，均表现为创伤处皮下软组织内逐渐增大的肿物。共发现22处病变，病灶均位于皮下脂肪与深筋膜之间；呈新月形(n＝14)、梭形(n＝4)和不规则形(n＝4)；包膜完整 (n＝18)或不完整(n＝4)，其中6例内部见膜状低回声。病灶最小范围2.5cm×1.1cm×0.4cm，最大范围10.5cm× 5.6cm×2.6cm。本组病灶内部68.2%呈极低回声（15/22）、31.8%呈不均质低回声（7/22）；极低回声中5例内部见脂肪结节，6例伴有膜状低回声；均伴有周边皮下脂肪层肿胀及回声增强，其中7例病变深部肌层肿胀。结论 MLL的超声表现有一定特征，多表现为皮下脂肪与深筋膜之间极低回声或不均质低回声包块，常有完整包膜，极低回声内可见膜样低回声或低回声脂肪结节,超声引导下穿刺抽吸有利于MLL诊断和治疗。 |

| ABSTRACT Objective To improve the accuracy of ultrasound diagnosis of the disease by analyzing and summarizing the characteristics of Morel-Lavallée lesion (MLL). Methods The clinical and ultrasound data of 22 cases of Morel-Lavallée lesion was retrospectively analyzed，which were clinically confirmed from March 2018 to May 2021. The contents of color Doppler ultrasonography are the lesion’s location, shape, size, internal echo characteristics, capsule, septation, and blood flow signal, etc. Results All of 22 cases had a clear history of trauma, all of which were gradually enlarged masses in the subcutaneous soft tissue of the wound. 22 lesions were found and located between the subcutaneous fat and deep fascia, and the shape was crescent-shaped (n=14), fusiform (n=4), or irregular (n=4), with intact capsule (n=18) or incomplete (n=4). Some membranous hypoechoic echo could be seen in 6 cases. The smallest size of the lesion was 2.5 cm×1.1 cm×0.4 cm, and the largest one was 10.5 cm×5.6 cm×2.6 cm. In this group, 68.2% of the lesions were weak echo (15/22), among them, fat nodules were seen in 5 cases and membranous hypoechoic structures were seen in 6 cases. And 31.8% were homogeneous hypoechoic (7/22). And 7 cases were accompanied by muscle edema around the lesions, all accompanied by swelling of the peripheral subcutaneous fat layer and enhanced echo. Conclusions Ultrasound manifestations of MLL have certain characteristics, most of which are weak echo or heterogeneous hypoechoic masses between subcutaneous fat and deep fascia, often with intact capsules. Sometimes there are some membranes hypoechoic contents and fatty nodules. Ultrasound-guided puncture is beneficial for the diagnosis and treatment of MLL. |
