【摘要】 目的 了解结核性与癌性胸腔积液超声显像特点，研讨两者超声鉴别诊断要点。方法 应用B型超声检查，回顾性分析50例结核性与癌性胸腔积液的超声显像特点。结果 结核性胸腔积液超声检查显示胸腔内胸腔积液无回声区透声清，胸膜均匀性增厚，液性暗区内未见实质性肿块；癌性胸腔积液超声检查显示胸腔内胸腔积液无回声区内充满细小光点，透声欠清，胸膜多呈非均匀性增厚，液性暗区内可见有实质非均质性肿块。结论 应用B型超声检查对于结核性和癌性两种不同性质的胸腔积液进行鉴别诊断，有较高实用价值。

    【Abstract】 Objective To find out the characteristics of ultrasonic imaging and visualization of tuberculosis hydrothorax and cancerous hydrothorax；to explore the essential of these two ultrasonic differential diagnosis.Methods Use type B ultrasonic examination to analyze retrospectively the characteristics of 50 cases with tuberculosis hydrothorax or cancerous hydrothorax.Results The ultrasonic examination of tuberculosis hydrothorax showed that hydrothorax in thoracic cavity had no echo zone with clear sound transparent；pleura was thickened uniformly；opaque dark area of fluid had no parenchymatous phyma.Ultrasonic examination of cancerous hydrothorax showed that hydrothorax in thoracic cavity had no echo zone filled with full of thin light spots；sound transparent was not very clear；pleura showed uniform thickening；opaque dark area of fluid had parenchymatous uniform phyma.Conclusion Using B ultrasonic examination to identify and diagnose tuberculosis hydrothorax and cancerous hydrothorax has highly practical value. ......
