Unusual case of a fetus with congenital cystic adenomatoid malformation of the lung associated with trisomy 13.

摘要

Congenital cystic adenomatoid malformation of the lung can be detected with antenatal ultrasound as hyperechogenic areas in the fetal chest. Associated extrapulmonary malformations as well as chromosomal aberrations are described as very rare.We present a case report of a fetus in the 23rd week of gestation who showed in the course of a routine ultrasound screening a large number of malformations: holoprosencephaly, arrhinencephaly, cleft palate, CCAM type III of the right inferior pulmonary lobe, ventricular septal defect and bilateral clubfeet. Chromosome analysis confirmed the suspicion of trisomy 13.The present case shows how important it is-even with malformations that are rarely accompanied by associated anomalies and which have a very good prognosis-to carry out a directed diagnosis including a fetal karyotyping.
