【摘要】：目的探讨小儿外伤性骨化性肌炎(PTMO)早期和成熟期的超声影像表现及其临床意义。方法选择2014年1月至2016年5月在深圳市儿童医院确诊的7例PTMO患儿,对其临床、病理检查结果及超声表现进行分析。结果 7例患儿中5例超声检查后经手术切除获得了病理诊断(2例为早期、3例为成熟期);2例经超声和MRI或CT影像检查确诊。2例早期PTMO超声表现为外伤局部的肌间低回声,边界清,内部显示纤细高回声,未显示明显钙化;能量多普勒显示枝条状血流信号。5例成熟期PTMO超声表现为低回声团块,内部显示条带状钙化,伴后方声影;彩色多普勒血流成像局部呈稀疏点状血流信号。结论超声检查可根据肿块的声像图表现,早期识别小儿PTMO,为临床诊断和治疗提供有用的信息。
[Abstract]:Objective to investigate the ultrasonographic features and clinical significance of traumatic ossifying myositis in children. Methods from January 2014 to May 2016, 7 cases of PTMO were diagnosed in Shenzhen Children's Hospital. The clinical, pathological and ultrasonic findings were analyzed. Results among the 7 cases, 5 cases were examined by ultrasound and then resected. Pathological diagnosis was obtained in 2 cases. 3 cases were diagnosed as early stage and 2 cases were diagnosed by ultrasonography and MRI or CT imaging. 2 cases of early PTMO showed hypoechoic intramuscular injury. The boundary was clear with thin and high echo in the interior without obvious calcification, and the flow signal of branch was detected in 5 cases of mature PTMO with hypoechoic mass and band calcification in the interior, accompanied by posterior acoustic shadow. The results were as follows: (1) in the boundary, there was no obvious calcification in the interior, and there was no obvious calcification in the interior. In color Doppler flow imaging, the local blood flow signals were sparsely punctate. Conclusion Ultrasonography can be used to identify early PTMOs in children and provide useful information for clinical diagnosis and treatment.
