We report on the prenatal diagnosis of partial trisomy 1q and monosomy X in a fetus with a congenital lung lesion and hydrops. The finding of hydrops in a fetus with a small lung lesion, congenital cystic adenomatoid malformation (CCAM) volume to head circumference ratio (CVR) 0.78, prompted cytogenetic analysis of amniotic fluid, revealing an unbalanced translocation between chromosomes X and 1 [46,X,der(X)t(X;1)(p11.2;q25 or q31)]. The incidence of chromosomal abnormalities with CCAM lesions is estimated at 1.6%. This is the first reported case of prenatally diagnosed partial trisomy 1q and monosomy X presenting as a fetal lung lesion and hydrops.
我们报告了一例患有先天性肺部病变和水肿的胎儿,其产前诊断为1q部分三体和X单体。在一名患有小肺部病变、先天性囊性腺瘤样畸形(CCAM)体积与头围比(CVR)为0.78的胎儿中发现水肿,促使对羊水进行细胞遗传学分析,结果显示X染色体和1号染色体之间存在不平衡易位[46,X,der(X)t(X;1)(p11.2;q25或q31)]。CCAM病变合并染色体异常的发生率估计为1.6%。这是首例报告的产前诊断为1q部分三体和X单体且表现为胎儿肺部病变和水肿的病例。
