摘　　要：经病理证实的６４例肺周围型恶性肿瘤及２３例肺周围型局限性良性病灶，用超声检查观察病灶形态、回声类型、病灶内细支气管显示分布状况、与肺组织边界的清晰度、相应局部胸膜等状况，可见良恶性病变有非常显著差异（Ｐ＜０．０１）。本组病例超声诊断结果为敏感性６１％（１４／２３例）；特异性９５％（６１／６４例）；总的诊断正确率８６％（７５／８７例）。超声对肺周围型占位病变的良恶性鉴别诊断有较高的临床价值，临床可广泛开展和应用。n 87 patients with peripheral pulmonary diseaseseither adhesive or close to the pleura, who were exam-ined, ultrasonographically 64 had lung cancer and 23benign lesions were confiimed histopathologically.Five sonographic features including configuration.echogenicity patterns, bronchial air phase in foci,margin, and pleural involvement were significantly different between malignant and benign diseases(P<0.01). The differential ultrasonography used inthis series showed a sensitivity of 61% (14/ 23), aspecificity of 95% (61 / 64), and an accuracy of 86%(75 / 87). The results demonstrate that ultrasound ishelpful in differentiating the malignant lesion from thebenign one in the peripheral lung near the pleura.
