彩色超声联合多平面成像技术诊断骨化性肌炎及分期

Color ultrasonography combined with multi-planar imaging in diagnosis of myositis ossificans and its staging

目的研究骨化性肌炎的超声表现,分析各期特征,为临床诊疗提供有力证据。方法选择37例骨化性肌炎患者,其中男性32例,女性5例;年龄24~52岁,平均年龄28岁。应用彩色超声及多平面成像技术筛查,经实时动态超声联合精确断层技术确诊,37例均行病理检查;结合确诊后病例的声像图,总结诊断依据。结果病理诊断为骨化性肌炎。术前超声诊断准确率达100%。其于病变早期表现为局限性边界清晰非均质实性稍低回声;中期为含稍强回声的非均质等回声;后期为含钙化的非均质稍强回声。结论彩色超声联合多平面成像技术可以依据各时期声像图表现诊断骨化性肌炎并确诊病变分期;为临床指导最佳治疗时期。

Objective To study the sonographic appearance and characteristics of myositis ossificans, and provide useful evidence for clinical diagnosis and treatment. Methods A total of 37 patients with myositis ossificans were enrolled, which included 32 males and 5 females, aged 24-52 years old with mean age of 28 years old. The color Doppler ultrasound and multi-planar imaging were performed to screen and confirm summarized diagnostic by real-time dynamic ultrasound combined with precise fault technology. Results All of them were myositis ossificans by pathological diagnosis, the preoperative accuracy of ultrasound diagnosis was 100 %. The myositis ossificans showed heterogeneous solid hypo-echoic with clear limitations boundary in early stage; the heterogeneous with slightly stronger echo in medium stage, and heterogeneous with slightly stronger echo contained calcification in later stage. Conclusion It is demonstrated that color Doppler ultrasound combined with multi-planar imaging could confirm myositis ossificans and pathological staging by the sonographic in each period, and guide the clinical selection of the best treatment period.
