Abstract
OBJECTIVE Many studies have shown that an increased nuchal translucency (NT) may be a good marker of fetal heart malformation, but the extent to which NT is suitable for identifying the population at risk remains unclear. We aimed to determine the value of NT measurement and of the presence of cystic hygroma colli in the screening of euploid fetuses for congenital heart defects (CHD). METHODS We carried out a retrospective analysis of 12 910 euploid pregnancies examined between January 1995 and August 2007 at our institution. The screening performance of NT measurements in identifying fetuses with CHD was assessed, with comparison between the use of cut-offs defined as absolute values, multiples of the median (MoM) and percentiles. The presence of cystic hygroma colli was also assessed in the prediction of CHD. RESULTS The incidence of major CHD was 3.4 per thousand (44/12 910). The sensitivity of NT measurement in screening for major CHD was 54.5% if the threshold was set at the 95(th) percentile, 45.4% if it was set at 3 mm, 27.3% for 3.5 mm, 50.0% for 1.5 MoM and 45.5% for 1.75 MoM. The false-positive rates for these thresholds were 8.4, 6.6, 1.7, 8.9 and 6.3%, respectively. The incidence of major CHD was 1.2% (10/813) in cases of thick NT (> 95(th) centile) and 4.3% (13/304) in cases of hygroma colli. CONCLUSIONS NT measurement during the first trimester is potentially useful for screening for fetal major CHD. Screening performance is consistent whether NT values are expressed as MoMs, percentiles or absolute values. The incidence of major CHD seems to be higher in cases of cystic hygroma colli.

Abstract
Lymphangioma is a rare benign tumor characterized by proliferating lymph vessels and composed of large cyst spaces with endothelium-lined channels of varying dimensions. The incidence of lymphangioma is approximately one in 6000 pregnancies. Less than 1% of lymphangiomas are purely mediastinal. The great majority of cases are of cystic lymphangioma, but very rarely there is a mixed lesion consisting of multiple cysts of dilated capillary and lymph vessels. We report a case of posterior mediastinal lymphangioma diagnosed at 28 weeks' gestation, in which three-dimensional ultrasonography was helpful in determining the precise location of the tumor. A Cesarean section was performed at 39 weeks and the tumor was resected on the 5(th) day postdelivery; histological examination revealed a mixed cystic lymphangioma.

Abstract
The ex-utero intrapartum treatment (EXIT) procedure is a technique designed to allow partial foetal delivery via caesarean section with establishment of a safe foetal airway by either intubation, bronchoscopy, or tracheostomy while foetal oxygenation is maintained through utero-placental circulation. The most common indication for the EXIT procedure is the presence of foetal airway obstruction, which is usually caused by a prenatal diagnosed neck mass. We report three cases of head and neck tumours with airway obstruction treated by means of EXIT and with different solutions in the management of the airway. With the involvement of Paediatric Otolaryngologists in EXIT, new indications and select variations from the standard EXIT protocol should be considered.

Abstract
OBJECTIVES We aimed to determine associated ultrasonographic findings, chromosome abnormalities and the prognostic factors of cystic hygromas in live-born infants. METHODS We reported a series of 57 cystic hygroma cases, who were diagnosed in the first and the second trimester of pregnancy by means of the ultrasonographic morphology of cystic hygroma, associated structural abnormalities, karyotype analysis and the autopsy findings. Survivors were followed for their fetal outcome and prognosis. RESULTS There were 57 new cases of cystic hygroma among 8,155 screenings (0.7%). 35 of the cases (61.4%) were nonseptated and 22 of the cases (38.6%) were septated cystic hygroma. Chromosomal abnormalities were found in 23 of the cases (40.3%). The most common abnormality in nonseptated cystic hygroma was trisomy 21 (8 cases, 25%) and in septated cystic hygroma was Turner syndrome (4 cases, 21.1%). The most common associated structural malformations were cardiac abnormalities (in 7 cases, 20%) in nonseptated cystic hygroma cases and nonimmune hydrops (in 12 cases, 54.5%) in septated cystic hygroma cases. Overall survival was poor; only one case of septated cystic hygroma with axillary location and seven cases of nonseptated cystic hygroma, of whom two died in the neonatal period, were alive (10.5%). This study had 80% power to detect 0.03% difference in diagnosis cystic hygroma (alpha = 0.05, beta = 0.80). CONCLUSION Fetuses with cystic hygroma are at high risk for adverse outcome. Prenatal diagnosis with invasive procedures should be done in order to inform the parents in detail. Axillary location of the hygroma and the depth of invasion had prognostic importance.

Abstract
Gastroschisis is a rare anomaly and it is usually not associated with other syndromic or nonsyndromic anomalies. The first case of gastroschisis with aneuploidy (Turner syndrome) is presented. A fetal huge cystic hygroma was diagnosed by prenatal sonography at 12 weeks of pregnancy and chorionic villi sampling (CVS) was performed. Cytogenetic analysis revealed 45, X0. The pregnancy was terminated by induction of labor at 16 weeks of pregnancy. The female fetus had a big membrane of cystic hygroma surrounding the fetal neck. Additionally, a full abdominal thickness defect with multiple loops of bowel outside the abdomen, which could not be diagnosed on prenatal ultrasound scan, was detected on postnatal examination.

Abstract
OBJECTIVE A prospective study of pregnancy outcome in fetuses with increased nuchal translucency above the 95th centile (group NT) or cystic hygroma (group CH) at 10 to 14 weeks of gestation was performed. PATIENTS AND METHODS Maternal and fetal data (nuchal translucency, caryotype, pregnancy outcome) and infant follow-up of 223 fetuses with first trimester nuchal translucency thickness (183 NT and 40 CH) were analysed. RESULTS The measurement of nuchal translucency thickness shows a significant difference between group CH and NT (7.4+/-2.9 mm compared 3.7+/-0.8 mm). Chromosomal abnormalities were present in 55% (22/40) in group CH, with 9 cases/22 (40.9%) of Turner syndrome, compared with 14.2% (26/183) in group NT with trisomy 21 in 15 cases/26 (57.7%) (P<0.05). The rate of unfavourable outcome of pregnancy (spontaneous abortion, elective termination of pregnancy, serious structural anomalies) was 80% (32/40) in group CH compared with 18% (33/183) in group NT (P<0.05). In chromosomally normal pregnancies, the rate of fetus with no visible serious structural anomalies was 44.4% (8/18) in group CH compared with 93% (146/157) in group NT (P<0.05). DISCUSSION AND CONCLUSION Our data show ultrasonographic evaluation of the fetal nuchal translucency thickness at the first trimester is actually indispensable. Neonatal outcome and malformation rate in fetuses with increased nuchal translucency or cystic hygroma are different, even with normal karyotype.

Abstract
OBJECTIVE To present the prenatal diagnosis of an interstitial 22q11.2 deletion involving a ring 22 chromosome associated with truncus arteriosus and a hypoplastic thymus. CASE Following the sonographic diagnosis of a cystic hygroma at 12 weeks of gestation, chromosome analysis revealed a ring 22 chromosome. RESULTS Ring chromosomes typically result in the deletion of genetic material from the distal long and short arms of the affected chromosome. The presence of an interstitial deletion in a ring chromosome is therefore unusual. FISH analysis revealed an unexpected deletion involving the TUPLE1 gene in the DiGeorge/Velocardiofacial syndrome region in 22q11.2. Maternal chromosome analysis revealed the cause of the apparent interstitial deletion, a paracentric inversion in the long arm of chromosome 22, resulting in the distal long arm of 22q being located adjacent to the centromere and the proximal end being located near the telomere. The fetus was subsequently diagnosed with truncus arteriosus and a hypoplastic thymus, consistent with DiGeorge syndrome. CONCLUSION The ring chromosome 22 found in the fetus appears to have been derived from a rearrangement of the mother's inverted 22, resulting in ring formation and loss of the end of the distal long arm of the inverted 22, including the TUPLE1 locus, causing DiGeorge syndrome in the fetus. The apparent interstitial deletion was actually a terminal deletion in a maternally inherited rearranged chromosome 22.

Abstract
Prenatal molecular genetic diagnosis for Noonan syndrome I is reported. Noonan syndrome was suspected because of large cystic hygroma colli, massive pleural effusion and ascites at 23 weeks of gestation and normal karyotype (46,XX). DNA was prepared from amnion cells and screened for mutations in the PTPN11 gene. In exon 8, a missense mutation (S285F) was found. Delivery was induced at 33 weeks of gestation because of silent cardiotocography (CTG). Despite immediate drainage of the hydrothorax, mechanical ventilation was insufficient and the child died 9 h after birth due to severe pulmonary hypoplasia. Pleural punctate was enriched for small lymphocytes and thus was characterized as chylus. Prenatal ultrasound findings in Noonan syndrome usually are unspecific and rarely lead to a diagnosis. However, with the combination of cystic hygroma, pleural effusion, ascites and normal karyotype Noonan syndrome should be considered and DNA testing for PTPN11 mutations may be appropriate. Malformations of lymphatic vessels and/or chylothorax in Noonan syndrome seem to be more frequent than usually anticipated.

Abstract
We present a case of fetal cystic lymphangioma that was initially diagnosed by ultrasonography and further evaluated by prenatal MR imaging. MR imaging findings aided in improved delineation of the neck mass. T2-weighted MR images revealed partial compression of the airway by the neck mass. This information was useful in the decision to use ex utero intrapartum treatment (EXIT) and helped surgeons in planning their approach to establish airway control during delivery.

Abstract
Prenatal diagnosis of a true fetal tetraploidy in direct and cultured chorionic villi: Tetraploidy is characterized by four complete sets of chromosomes (4n= 92). Although it has been frequently reported in spontaneous abortions, tetraploidy is extremely rare in term pregnancy. Most of late surviving patients are diploid/tetraploid mosaics and present severe mental and physical impairment. Up to date, only five tetraploidies were ascertained in the prenatal stage in amniocytes and/or fetal blood lymphocytes. No one has been reported in chorionic villi probably because tetraploidy is generally considered in this tissue as a false positive result due to confined placental mosaicism (CPM) or placental culture artefacts. We report here on a case of tetraploidy detected in chorionic villi because of fetal cystic hygroma. We discuss the reliability of this diagnosis and propose guidelines in the follow-up of tetraploidies detected after chorionic villus sampling (CVS). Thus a misdiagnosis of this poor condition will be avoided at best and an appropriate genetic counseling will be given to the parents.

Abstract
Lymphangiomas are benign tumours of the lymphatic system. Early prenatal diagnosis is important to permit a planned delivery and provide adequate postnatal care. It thereby improves prognosis and allows the option of terminating the pregnancy if poor outcome is predicted. We report two cases, a giant haemangiolymphoma and a lymphangioma. 2D and 3D US findings are presented and differential diagnosis, therapeutic options and prognosis are discussed.

Abstract
BACKGROUND In recent years, an increasing amount of experience has been collected in measuring the nuchal translucency (NT) of the fetus in early pregnancy. While all fetuses develop a measurable collection of fluid in the area of the neck between the 11th and 14th weeks of pregnancy, the fact that fetuses with chromosomal disorders, cardiac defects, and syndromal diseases, in particular, reveal an above-average incidence of increased NT has been noticed. OBJECTIVE By processing our own patient data from the past two years, we intend to elucidate the question of whether NT measurement is a sensible investigation for the early detection of fetal problems. PATIENTS AND METHOD NT measurements were carried out in 199 fetuses; these measurements were standardized according to the guidelines of the Foetal Medicine Foundation in London, in whose multicentric study we are participating. The patients were under the care of our prenatal diagnosis and therapy department and were referred to us from external sources. RESULTS NT within the reference range was determined in 152 fetuses; NT exceeded the reference value in 47 fetuses. Of those fetuses with increased NT, 7 fetuses revealed a chromosomal anomaly, 1 foetus was suffering from a cardiac defect, 3 fetuses were suffering from other organ abnormalities, and 3 fetuses were determined to be suffering from syndromal disease. None of the fetuses whose NT measurements were within the reference range was discovered to be suffering from any of the above-mentioned problems. CONCLUSION Even this relatively small group of patients reveals that NT measurement is a very effective filter for detecting certain fetal diseases during the early fetal period.

Abstract
OBJECTIVE The purpose of this study was to describe a characteristic cluster of sonographic features of fetuses with Turner syndrome in early pregnancy. STUDY DESIGN A targeted transvaginal ultrasound examination of all fetal organs was performed for 40123 consecutive pregnant women at 14 to 16 weeks of gestation. Both low- and high-risk pregnancies were included. Fetal karyotyping was performed in 9348 cases. The main indications were major fetal anomalies, advanced maternal age, abnormal biochemical markers, maternal anxiety, and request. RESULTS Turner syndrome was detected in 13 fetuses (0.03%, 1/3086 early pregnancies). Huge septated cystic hygroma, severe subcutaneous edema, and hydrops were observed in all cases. A short femur was detected in 12 of 13 fetuses. A narrow aortic arch was visualized in all 8 fetuses who were scanned after 1995, when scanning of the aortic arch became mandatory in our institution. Four other fetuses had three or four of the five markers, 2 of the fetuses had trisomy 21, 1 fetus was normal, and one case of missed abortion occurred without a karyotype. CONCLUSION A reliable diagnosis of Turner syndrome by sonographic means is possible in early pregnancy.

Abstract
BACKGROUND The aim of this study is to analyse several theories of pathogenesis of cystic hygroma, its correlation with chromosomal abnormalities and the indicators of poor or good prognosis. METHODS EXPERIMENTAL DESIGN This is a retrospective study that evaluates all cases of cystic hygroma seen during the four-year period from January 1994 to December 1997. SETTING This study was performed in the center of prenatal diagnosis of institutional hospital in Caserta. PATIENTS All cases of fetuses with cystic hygroma were examined in 2100 pregnant female who visited the ambulatory. INTERVENTIONS The modality of diagnosis of this pathology and the presence of abnormal maternal serum levels of alpha-fetoprotein, human chorionic gonadotropin and unconjugated estriol were evaluated. Moreover, the presence of karyotype abnormalities or other non chromosomal abnormalities were also evaluated. Prognostic indicators such as the presence of septae seen by sonography were examined. RESULTS Nine fetuses with cystic hygroma were diagnosed sonographically. Septae were identified in six cases. Chromosomal abnormalities were found in five cases. Two cases presented Turner's syndrome and one case Downs' syndrome. There were two cases with associated anomalies. The amniotic fluid alpha-fetoprotein (AFP) levels were high in all cases. CONCLUSIONS Cystic hygroma is a malformation of the lymphatic system that is diagnosed by ultrasound very well from the first quarter of pregnancy. It is frequently associated with chromosomal and non chromosomal abnormalities. The presence of septae in it and amniotic fluid AFP levels are prognostic indicators.

Abstract
Airway compromise at birth can be anticipated with giant neck masses, so that as much anatomic information as possible is necessary prior to delivery to establish a diagnosis and assess the airway. With this study, we evaluated the usefulness of prenatal magnetic resonance imaging (MRI) for evaluation of giant fetal neck masses prior to operating on placental support, the Ex Utero Intrapartum Treatment (EXIT) procedure, performed to secure the neonatal airway. Three pregnant women with an ultrasound (US) diagnosis of fetal giant neck mass were referred for prenatal MRI. As this was our initial experience performing prenatal MRI, a variety of imaging sequences were used including spin-echo, fast gradient-echo, half-fourier single shot turbo spin-echo (Haste), and echo-planar imaging (EPI). All sequences performed were able to demonstrate the fetal airway relative to the mass. In addition, the images were able to give a more global definition of the mass because of the larger field of view than could be obtained with MRI compared to US. The Haste sequence provided the best definition of a mass because of decreased motion artifacts. The prenatal diagnosis on MRI was teratoma in two and lymphangioma in one and was confirmed at birth. MRI provided essential information about the diagnosis and the anatomy of the giant neck masses and adjacent airway in three fetuses prior to selection for the EXIT surgical procedure.

Abstract
OBJECTIVE Our purpose was to determine whether fetal specimens, including pleural, ascitic, pericardial, facial, and cystic hygroma fluid or urine, are suitable sources for accurate chromosomal analysis. STUDY DESIGN Thirty-nine samples of fetal fluid (pleural, n = 11; ascitic, n = 5; pericardial, n = 1; lung cyst, n = 1, facial cyst, n = 1; cystic hygroma, n = 7; and urine, n = 13) were cultured and analyzed with standard cytogenetic techniques for lymphocytes or amniotic fluid. These samples were obtained as part of the routine obstetric investigation and management. Conventional backup samples were also obtained. RESULTS Karyotyping was successful in 34 of 39 samples. Cells were harvested from all pleural samples, three ascitic samples, and one hygroma fluid sample in 2 to 4 days from 11 urine samples, one ascitic sample, and the remaining six hygroma samples in 7 to 11 days. Five cultures were unsuccessful. Samples with high lymphocyte counts yielded results as quickly as fetal blood. CONCLUSION The use of "alternative" samples of fetal fluids for karyotyping may be considered when amniotic fluid or fetal blood is difficult to obtain. In selected cases this approach avoids the unnecessary risk of additional invasive procedures solely to obtain a karyotype.

Abstract
A case of monozygotic twins in a 19-year-old primigravida is presented. Ultrasound examination at 15 weeks' gestation showed one twin to have a cystic hygroma and hydrops fetalis. The other twin appeared normal. The twins appeared to occupy the same amniotic cavity. Fluid was taken from the cystic hygroma under ultrasound guidance for karyotyping and this showed 45,XO chromosomes. Conservative management was adopted. Serial ultrasound examination showed deteriorating hydrops and at 26 weeks the first twin died. Intensive monitoring of the remaining twin was undertaken with weekly ultrasound, cardiotocography (CTG), and clotting screens. At 29 weeks' gestation the CTG and clotting were normal, but ultrasound revealed that multicystic encephalomalacia had developed in the second twin. A very thin dividing membrane was seen for the first time between the twins. The parents decided to terminate the pregnancy. Prior to an intracardiac potassium chloride injection, a fetal blood sample was taken which revealed 46,XX chromosomes and a normal clotting screen including natural anticoagulant levels. Labour was then induced. Delivery took place 5 h later and the woman made an uneventful recovery. The mechanism for genetic differences between monozygotic twins is discussed and the literature reviewed. A non-disjunction event around the time of splitting of the twins is proposed as the cause. The prognosis for the remaining twin is also discussed, as is the pathogenesis of the cerebral damage.

Abstract
Over a 5-year period, the author examined the posterior nuchal region of the fetus in 7200 first- and second-trimester sonograms. Nuchal fluid collections were analysed to differentiate physiologic collections, which resolve spontaneously, from pathologic ones, which necessitate invasive testing for chromosomal abnormalities. Recommendations for evaluating ultrasonographic findings, based on the results of the study, are presented algorithmically in this pictorial essay. A single echogenic line representing a skin reflection was usually visible in normal fetuses. Thin double echogenic lines, observed in eight cases in this series, were due to fetal rotation or the presence of an amniotic membrane adjacent to the normal dorsal pseudomembrane and were not indicative of abnormality. In three cases the spectral reflection of the fetal neck surface was relatively thick, leading to the appearance of thick double echogenic lines; of these, two cases involved Down's syndrome. Therefore, karyotyping is suggested in all cases of thick echogenic lines. Of the 11 nuchal fluid collections up to 5 mm in diameter observed in this series, 10 resolved spontaneously by 24 weeks gestational age. In the other case the collection enlarged, and karyotyping revealed Turner's syndrome. Of the 16 cases of nuchal fluid collections greater than 5 mm in diameter, 5 were associated with an abnormal karyotype (Down's syndrome in 4); karyotyping is recommended in all such cases. Nuchal edema occurred in 22 cases. It was associated with Down's syndrome in 8 cases and with trisomy 18 in 1 case. Among fetuses with nuchal edema, the frequency of aneuploidy was substantially greater if other abnormalities were also present.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We studied the outcome of fetuses in whom cystic hygroma was diagnosed in the first and early second-trimester of pregnancy using transvaginal ultrasonography. The purpose of this study was to evaluate the association between fetal cystic hygroma and fetal cytogenetic abnormalities, and the long-term prognosis. Thirty-five consecutive fetuses between 9.1 and 13.4 weeks of gestation diagnosed as having a nuchal hygroma were evaluated ultrasonographically and karyotyped. Those with a normal chromosome complement were ultrasonographically monitored throughout the remainder of the pregnancy to document the resolution of the hygroma. Eighteen of thirty-five fetuses were found to have a normal karyotype and five of these were aborted electively. The hygromas resolved in ten of these karyotypically normal fetuses within four weeks of initial diagnosis and they were phenotypically normal at birth. Seventeen fetuses were karyotypically abnormal with trisomy twenty-one being the most common abnormality. Prenatal cytogenetic analysis should be offered to women with fetal cystic hygroma diagnosed in the first trimester. A normal outcome is likely in those without chromosome abnormalities.

Abstract
Cystic hygroma of the neck (CHN) is the result of a defect in the embryonary development of the lymphatic system. In many cases foetal ultrasound allows an early diagnosis before birth, the prognosis being very different according to the gestational age at the time of detection. When discovered before 30 weeks of gestation it is almost always associated with chromosomal abnormality and/or polymalformation leading to spontaneous or therapeutic abortion. On the contrary when appearing after the 30th week of gestation, CHN is usually an isolated malformation as when discovered during infancy or childhood. Approximately 2/3 of these "late" CHN are present at birth; 90% are discovered before 2 years of age. A spontaneous regression occurs in about 15% of the cases. In 70% of cases the CHN is simple without extension to the oropharynx or mediastinum and its complete surgical resection is usually easy. Extension to the oropharynx is present in about 20% of the cases; there is a risk of neonatal respiratory distress and the treatment is difficult. Extension to the mediastinum is found in about 10% of the cases; respiratory distress is rare and a large surgical resection is necessary. Surgery is the primary treatment of CHN after a careful evaluation of the extension of the tumor by ultrasound, scanography or nuclear magnetic resonance, and oropharyngeal endoscopy. It allows a "macroscopically complete" resection in about 80% of the cases, but a recurrence is observed in approximately one every five cases. Following partial resection or important recurrence, treatment includes according to the cases; new attempt of surgical resection, sclerosing therapy, and laser therapy for the oropharyngeal forms.
