作者比较了34例近胸壁的原发性肺癌对胸壁和胸膜侵犯的超声波和CT诊断的准确性。超声波诊断壁层和脏层胸膜受累的平均准确性是62％,CT是74％。超声波和CT都有过高估价病变的倾向。13例患者,超声未作出准确的诊断,其中69.2％有胸膜凹陷。外科术中错误估价的病例也是有胸膜凹陷者。CT过高估价的有3例,其中2例有肺不张,另1例为胸膜粘连。超声波误诊的主要原因也 The authors compared the accuracy of ultrasound and CT diagnosis of chest wall and pleural invasion in 34 cases of primary lung cancer in the chest wall. The mean accuracy of ultrasonic diagnosis of pleural involvement in the parietal and visceral layers was 62%, and CT was 74%. Both ultrasound and CT tend to overestimate the lesions. In 13 patients, ultrasound did not make an accurate diagnosis, and 69.2% had a pleural depression. Cases of misvaluation during surgery were also those with pleural indentation. There were 3 cases of overestimation of CT, of which 2 cases had pulmonary atelectasis and 1 case had pleural adhesions. Misdiagnosis of ultrasound is also the main reason
