摘　　要：目的探讨早产儿支气管肺发育不良(BPD)的早期影像表现,提高BPD的早期诊断能力。方法回顾分析经临床诊断为BPD的17例早产儿胸部影像表现。结果17例早产儿中,胸片无明显异常5例,继发于其他胸部原发疾病12例。胸片显示两肺野模糊,肺透光度减低5例;原发病病程持续2～4周,异常征象不消失,且连续照片变化不明显者4例。CT主要表现为肺野呈毛玻璃密度及实变影6例,肺过度充气、大小不一囊状透亮影10例,粗网格状影呈两肺弥漫性分布4例。结论虽然早产儿支气管肺发育不良的诊断主要依据临床病史,但早期影像表现仍具有诊断价值,胸部薄层CT上多发囊状影是诊断BPD的重要征象,连续影像随访有助于该病的早期诊断。OBJECTIVE To study the early radiological image manifestations of the bronchopulmonary dysplasia（BPD） of the premature infants in order to improve the ability of the early diagnosis of BPD. METHODS To review and analyze the radiologieal image manifestations in chest of 17 definite cases of BPD of the premature infants with final diagnosis. RESULTS Among them, 5 cases had no apparently abnormal images; 12 cases secondarily developed some other primary thoracic diseases.5 cases presented clouding images with comparatively reduced degrees of transmittance of the two lung fields ; 4 cases＇ developing courses of their primary diseases lasted for 2 to 4 weeks, without any disappearing sings of abnormality, and without, in addition, any apparent changes according to theircontinuous pictures; 6 cases＇ main manifestations of the two lung fields, in accordance with their Computer Tomography（CT）, presented a clouded glass-shaped density and consolidated shadows; 10 cases had over-charged lungs, while light0transmitted shadows appeared with differnt sizes and with capsule-like shapes; 4 cases displayed their two lungs widespread with thicklattice-like shadows. CONCLUSIONS Although the diagnosis of the bronchopul monary dysplasia based mainly on its clinical history, an early radiological image manifestation owns its own value.Meanwhile the widespread capsule-like shadows in the thoracic thin-layer CT films are the sign.ificant signs through which BPD can be promptly detected and the continuous radiological follow-ups help a lot to obtain an early diagnosis of the disease.
