目的：探讨胸壁骨肿瘤的超声诊断价值。方法：采用超声波诊断仪对４８ 例胸壁骨肿瘤进行检查，观察其各类骨肿瘤的声像图特点。结果：声像图为低回声肿块并有光滑弧形内侧壁和锥形边者占７９．２％ ，高回声肿块有锥形边者为１２．６％ ，无锥形边者２０．８％ ，胸壁肿瘤均有与胸壁同步运动的征象。结论：对肋骨及胸骨的肿瘤可较清晰显示，对其定位诊断准确性可达１００％ ，在超声引导下活检对胸壁恶性肿瘤的诊断准确率达９５％ 。
Objective: To investigate the diagnostic value of ultrasound in chest wall tumors. Methods: Forty-eight cases of thoracic bone tumor were examined with ultrasonic diagnostic apparatus, and the sonographic features of various types of bone tumors were observed. Results: The echographic picture showed hypoechoic mass with 79.2% of smooth arc medial wall and conical edge, 12.6% of hyperechoic mass with conical edge and 20.8% of non-conical edge. , Chest wall tumors have signs of synchronous motion with the chest wall. Conclusion: The tumors of ribs and sternum can be clearly shown, the diagnostic accuracy of the diagnosis can reach 100%. The diagnostic accuracy of biopsy for malignant thoracic tumors by ultrasound is 95%.
