Severe Congenital Diaphragmatic Hernia With Trisomy 9: A Case Report and Review of the Literature

Congenital diaphragmatic hernia (CDH) is known to be complicated with various chromosomal abnormalities. However, the grade of pulmonary hypoplasia of CDH complicated by trisomy 9 is not known. This information is essential to the mother who has had a fetus with the same complication. We report a ca...

Sumario:Congenital diaphragmatic hernia (CDH) is known to be complicated with various chromosomal abnormalities. However, the grade of pulmonary hypoplasia of CDH complicated by trisomy 9 is not known. This information is essential to the mother who has had a fetus with the same complication. We report a case of severe CDH with trisomy 9. The fetus had fetal growth restriction and multiple anomalies, including severe left CDH (observed/expected lung-to-head ratio 13.7%, liver-up, stomach grade 3 in Kitano classification), mild ventriculomegaly, low-set ear, rocker bottom, and single umbilical artery. Chromosomal test by amniocentesis showed a karyotype of 47,XX,+9. The neonate was born alive at 34 weeks but died 49 minutes after birth. In the literature review, this case and seven cases of complete trisomy 9 had CDH, and four of them were explained as "large" or "severe" CDH. In conclusion, trisomy 9 might be occasionally complicated by severe CDH.
