目的　进一步提高胸部淀粉样变主的影像认识。方法　搜集 3例经病理证实的淀粉样变胸部影像资料 ,3例胸部X线平片 ,2例CT扫描 ,1例心脏超声检查。结果　淀粉样变胸部影像表现有 :气管—支气管壁增厚 ,肺不张 ,少量胸腔积液 ,胸膜增厚 ,肺间质增生 ,心脏增大。结论　胸部淀粉样变影像表现结合临床可提示诊断 ,但鉴别诊断仍需依赖病理。 Objective To further improve the imaging knowledge of the amygdala in the chest. Methods Three cases of pathologically confirmed amyloidosis were collected. Three cases of chest X-ray, two cases of CT scan and one case of echocardiography were collected. Results Amyloidosis of the thoracic image showed: tracheal - bronchial wall thickening, atelectasis, a small amount of pleural effusion, pleural thickening, pulmonary interstitial hyperplasia, cardiac enlargement. Conclusion Chest amyloidosis with clinical manifestations may be prompted to diagnose, but the differential diagnosis is still dependent on the pathology.
