Turner Syndrome and Cystic Hygroma

چکیده
Fetal nuchal cystic hygromas (NCH) are congenital malformations of the lymphatic system and can be defined as an area of sonolucency in the soft tissue of the occipital region, consisting of two symmetrical cavities completely separated by a midline septum (nuchal ligament), with or without internal trabeculae (multiloculated cysts). Diagnosis can be made at first trimester of pregnancy using vaginal ultrasonography (1). Cystic hygromas may subsequently disappear, thus emphasizing the importance of an early ultrasonographic examination. The association with chromosomal abnormalities has been reported in many studies (2-9) and therefore, fetal karyotype evaluation must be routinely carried out in these cases. The most common chromosomal abnormality associated with cystic hygroma is 45 XO (in 60% of all patients). Trisomy 13, 18, 21 and 47XXY are among other common chromosomal abnormalities(4-8). It is very difficult to determine the prognosis of a fetus with cystic hygroma since it may occur as an isolated finding or may be associated with chromosomal abnormalities (4), Mendelian TURNER SYNDROME AND CYSTIC HYGROMA

Fetal nuchal cystic hygroma associated with aortic coarctation and trisomy 21: a case report
We report a case of fetal nuchal cystic hygroma associated with aortic coarctation and trisomy 21. A stillborn baby, delivered at 15 weeks and 5 days of gestation, had a huge nuchal cystic hygroma. Autopsy revealed aortic coarctation of the periductal type with patent ductus arteriosus, endocardial cushion defect and left ventricular hypoplasia. Trisomy 21 was evident by karyotyping. Macroscopi...

Cystic cervical hygroma or cervical cystic lymphangioma is a congenital benign disease of the lymphatic system that is characterized by the accumulation of lymph in the jugular lymphatic sacs of the nuchal region. The factor that causes this pathology is not clarified yet but the physiopathological mechanism seems to be multifactorial. The incidence and prevalence of cervical hygroma are increa...

Cystic Hygroma is a well-recognized lesion in paediatric patients but it is very rare in adults. We report here a case of Cervical Cystic Hygroma in a 45 yr old male. The reasons to present this case are 1) Its rarity in adults 2) Unusual age of presentation 3) Simulates various benign and malignant lesions at this site 4) Is a diagnostic challenge and 5) Role of histology for definitive postop...
متن کاملUllrich-Turner syndrome in an XY female fetus with deletion of the sex-determining portion of the Y chromosome.
Here we describe a fetus in whom a cystic hygroma was detected by ultrasound during the second trimester. Autopsy demonstrated a female fetus with manifestations of Ullrich-Turner syndrome, including gonadal dysgenesis, generalized lymphedema, and preductal aortic coarctation. Surprisingly, the karyotype was 46,XY, with no evidence of mosaicism for a 45,X cell line. Y-DNA hybridization studies ...
متن کاملTrisomy 13, 18, 21, Triploidy and Turner syndrome: the 5T’s. Look at the hands
First trimester spontaneous abortions occur in 15 to 20% of all clinically recognized pregnancies. Chromosomal -anomalies are responsible for more than 50% of spontaneous abortions. The majority (90%) of these chromosomal anomalies are numerical, particularly autosomal trisomies (involving chromosomes 13,16, 18, 21, 22), polyploidy and monosomy X. At birth chromosomal anomalies are still an imp...
