[Prenatal diagnosis and obstetric management in association of hydramnios and homozygosity].
The patient was referred to hospital in the 29th week of gestation owing to polyhydramnions. Ultrasonography revealed isolated left-sided hypertrophy (from foetal chest to the lower extremity) with subcutaneous lymph cysts. Amniocentesis for genetic examination revealed a chromosomal disorder showing homozygous t(13q, 14q) translocation. This extremely rare anomaly could be explained only and was finally proven by a father-daughter incest. The authors underline the necessity of karyotyping as well as the ultrasonic exclusion of foetal malformations in patients with polyhydramnions.
