The aim of our study aim was to report the case of a fetus with Turner syndrome TS higgroma by karyotype from cystic hygroma CH fluid, highlighting the applications and importance of this procedure.
First-trimester screening revealed an increased nuchal translucency measurement, cervical cystic hygroma and head and trunk subcutaneous edema. The presence of oligohydramnios prevented the performance of amniocentesis. We performed puncture of the CH for fetal karyotyping, which revealed X-chromosome monosomy 45,Xcompatible with TS.
Therefore, the use of CH fluid as an alternative sample for fetal hivroma may be considered when conventional invasive procedures can not be performed. The aim of our study was hihroma report a fetus with Turner syndrome TS diagnosed by karyotype from cystic hygroma CH fluid, emphasizing the applications and importance of this procedure.
A year-old healthy pregnant woman was in her third pregnancy and had a history of two previous miscarriages all occurred during the first trimester. There was no family history of birth defects or genetic disorders. First-trimester screening revealed an increased nuchal higrma measurement 7 mmcervical cystic hygroma and head and trunk subcutaneous edema.
Ascites was also noted later. There was oligohydramnios, which prevented the execution of amniocentesis.

Therefore, at 18 weeks of pregnancy, a puncture of the CH was held for fetal karyotyping, following a long-term culture. Chromosomal analysis showed a X-chromosome monosomy – 45,X, consistent with TS. At 21 weeks, there was no fetal heartbeat and spontaneous elimination of the fetus occurred two days later. TS is a multisystemic disorder characterized by partial or total X-chromosome monosomy, seen in 1: It can be diagnosed at different life stages, including the intrauterine period.
Ultrasound findings, such as CH and hydrops, may assist in its detection 1. Prenatal diagnosis is usually performed by karyotype analysis from amniotic fluid samples.
However, as found in the present cistido, this type of sample or even fetal blood by cordocentesis becomes unable to obtain due to obstructions by large cysts or oligohydramnios 2.
The use of CH fluid, obtained through direct hygroma puncture, can be used as an alternative procedure 2. Fetal CH is characterized by single or multiple lymphatic congenital cysts and is often found associated with TS 3. The procedure is similar to amniocentesis and has low higgroma rate. If the CH is multiloculated, it is possible to puncture and analyze different regions especially due to the possibility of mosaicism 4.
The karyotype is performed through lymphocyte culture from cystic cells that has a mitotic index and metaphases quality compatible with a blood lymphocyte culture.

The karyotype test results using CH puncture are obtained in four days, while by amniocentesis they range from days 5 Figures 1 and 2. In our study, the performance of the fetal karyotype by CH puncture allowed the correct diagnosis and genetic counseling.
Despite the advanced maternal age, TS is not associated with it. Moreover, the diagnosis was important to assess the hitroma. Thus, the use of alternative samples for fetal karyotyping, such as CH fluid, may be considered when conventional invasive procedures can not be performed. J Clin Endocrinol Metab.
