摘要
目的探讨肌骨超声、多层螺旋CT(MSCT)应用于肱三头肌肌腱断裂伴骨化性肌炎临床诊断价值。方法回顾性分析10例肱三头肌肌腱断裂伴骨化性肌炎患者肌骨超声及MSCT影像特征,分析其诊断价值。结果早期、中期、晚期病变分别1例、5例、4例,超声发现在肱骨滑车近处肱三头肌肌腱纤维呈连续性中断,两断端中间呈不均质低回声,近侧断端肌腱回缩增厚,不规则、多层强回声,与边缘分界不清,MSCT显示早期呈条状肿块,边缘见斑点状稍高密度钙化灶,3例中期病变从内至外呈等-稍高-高密度"分层"征象,2例病变周围边缘呈弧形"蛋壳样"钙化,晚期病变边界清晰,累及骨皮质但髓腔不受累,周围无软组织肿块,1例显示分叶状骨化块,中央镂空为软组织。结论肌骨超声、MSCT应用于肱三头肌肌腱断裂伴骨化性肌炎有较高临床诊断价值,能准确判断分期,指导临床确定最佳治疗时期。
Objective To analyze the clinical value of musculoskeletal ultrasound and multi-slice spiral CT (MSCT) in the diagnosis of tendinousrupture of triceps complicated with myositis ossificans.Methods The musculoskeletal ultrasound and MSCT image features of 10 patients with tendinousrupture of triceps complicated with myositis ossificans were retrospectively analyzed.The diagnostic value was analyzed.Results There were 1 case with early lesions,5 cases with metaphase lesions and 4 cases with advanced lesions.Ultrasound showed that the tendon fiber of triceps at the proximal trochlear were continuously interrupted.The place between two interrupt showed heterogeneous hypoechoic.The proximal tendon tendon at the broken side was retracted and thickened. There were irregular multi-layered strong echoes with unclear boundaries.MSCT shows strip-like mass in the early.There was a spotted slightly high-density calcification at the edge.There were 3 cases with metaphase lesions showing stratification sign of similarslightly high-high-density from the inside to the outside.There were 2 cases with curved eggshell-like calcification in the margin around the lesions.The boundary of the late lesion was clear,involving the bone cortex but not involving the medullary canal,without soft tissue mass around.There was 1 case showing a lobulated ossification block.And the central hollow was soft tissue.Conclusion The application of musculoskeletal ultrasound and MSCT on tendinousrupture of triceps complicated with myositis ossificans is of high clinical diagnostic value.It can be used to judge the stage accurately,and guide the clinic to determination the best treatment period.
