【摘要】 目的探讨胎儿支气管源性囊肿的产前超声声像图特征,分析漏误诊原因。方法分析12例支气管源性囊肿的临床资料和超声声像图特征。结果 12例胎儿出生后手术及病理证实为支气管源性囊肿,纵隔型8例(其中3例合并肺囊腺瘤样畸形),肺内型3例(其中1例合并肺隔离症),异位型1例(合并肺隔离症)。7例产前超声发现了支气管源性囊肿病灶;4例只发现了肺内合并的病灶,漏诊了肺外的支气管源性囊肿病灶;1例产前超声未发现病灶。在产前超声发现的7例胎儿中,单发囊性病灶5例,囊实性病灶2例;3例诊断为支气管源性囊肿,诊断符合率25%,4例误诊为肺囊腺瘤样畸形。结论胎儿支气管源性囊肿容易合并肺囊腺瘤样畸形、肺隔离症,产前超声明确诊断有一定的困难。产前超声的价值在于发现并定位病灶,同时评估肿块对肺组织、气管的压迫及纵隔移位的情况。更多还原

【Abstract】 Objective To explore the ultrasonographic features of the fetal bronchogenic cyst,and analyse the causes of misdiagnosis and missed diagnosis.Methods To retrospectively analyze the clinical data and ultrasonographic features of 12 cases of fetal bronchogenic cyst by prenatal ultrasonography and compared with pathology.Results12 cases were confirmed bronchogenic cyst by surgery and pathology after birth,8cases with mediastinal bronchogenic cyst(including 3cases with congenital cystic adenomatiod malformation),3cases with intrapulmonary bronchogenic cyst(including 1case with bronchopulmonary sequestration),1case with ectopic bronchogenic cyst(combine with bronchopulmonary sequestration).7cases of bronchogenic cyst were found by prenatal ultrasonography,4cases were only found in merge lungs of lesions,missed diagnosis the extrapulmonary bronchogenic cyst lesions,1case was not found by prenatal ultrasonography.Of the 7cases founded by prenatal ultrasonographic,5lesions were single cystic masses,2lesions were cyst solid masses.3cases were diagnosed as bronchogenic cyst,the rate of correct diagnosis was 25%,4cases were misdiagnosed as congenital cystic adenomatiod malformation.Conclusions The qualitative diagnosis of bronchogenic cyst by prenatal ultrasonographic is still difficult,because bronchogenic cyst easily combine with congenital cystic adenomatiod malformation and bronchopulmonary sequestration.The value of prenatal ultrasonography is to find and locate the lesions,meanwhile to evaluate the oppression of the lesions to lung tissue,trachea and mediastinal shift.更多还原
