Consanguineous partners had a boy with campomelic dysplasia who died of increasing respiratory distress soon after birth. The next pregnancy was monitored frequently by ultrasonography and a healthy male infant was born at term. During a further pregnancy, ultrasonography suggested campomelic dysplasia in the 16th week of gestation. This was confirmed in the 18th week. The pregnancy was terminated and the fetus showed the typical radiological, anatomical and histological findings. 相似文献

Diastrophic dysplasia, an autosomal recessive disorder, results in severe short-limbed dwarfism, progressive spinal and joint problems, and secondary psychosocial disability. The results of treatments are unsatisfactory. Four pregnant mothers at risk for an affected fetus were studied with an ultrasound scanner at 16 and 19 weeks of gestation. Each mother had a previous child with diastrophic dysplasia. The biparietal distance and the length of the long bones of the extremities were normal in three fetuses, whereas in one fetus there was a 30 per cent shortening of all long bones. The biparietal distance corresponded with the gestational age in all fetuses. In one fetus, diastrophic dysplasia was confirmed by fetoscopy and fetal radiograph at 19 weeks of gestation after the parents had decided to terminate the pregnancy. The skeletal radiograph and autopsy findings of the fetus verified the diagnosis. All other mothers were followed with repeated ultrasound examinations, and they delivered healthy babies. The retrospective follow-up of the four previous pregnancies and of the present one with affected fetuses disclosed that two mothers had had vaginal bleeding, two lymphedema, one abdominal pains, and one mother had had polyhydramnios. These complications were, however, mild and transient, and they could not be regarded as specific for pregnancies with affected fetuses. 相似文献

Chondroectodermal dysplasia (Ellis-van Creveld syndrome) has previously been diagnosed prenatally only once, using fetoscopy. We report on two consecutive pregnancies in a woman at risk of having a child with the syndrome during which fetoscopic visualization was performed. Ellis-van Creveld syndrome was diagnosed prenatally in one instance, while it could be excluded in the other one. Non-invasive prenatal diagnosis of the syndrome is discussed. 相似文献

In a pregnant woman without increased genetic risk, the presence of distrophic dysplasia of the fetus was diagnosed sonographically at 31 weeks' gestation and definitively distinguished from other skeletal dysplasias. In all prenatal diagnoses of diastrophic dysplasia reported so far, this autosomal recessive congenital condition had occurred in the family's previous children and this made the diagnoses of fetal diastrophic dysplasia easier. The reported case was diagnosed due to evidence of an extreme shortening of all long bones of the extremities associated with other skeletal deformities which, taken as a whole, are typical of this syndrome: micrognathia, cervical kyphosis, persistent extension limitation in elbow and knee joints, club feet, ulnar diviation of hands, shortened phalanges, and, in particular, abduction of thumbs (‘hitchhiker thumbs’) and big toes. 相似文献

Prenatal diagnosis of heterozygous achondroplasia at 25 weeks is described. First-level fetal ultrasonography demonstrated short long bones of the lower limbs. Second-level examination showed a large head; shortened femur, fibula, and tibia; a ‘trident’-shaped hand; and an abnormal facial profile. 相似文献

Atelosteogenesis type II is a lethal chondrodysplasia characterized by severe micromelia, spinal abnormalities, talipes equinovarus, and abducted thumbs and toes. We present a case diagnosed at 21 weeks of gestation in which antenatal sonographic and post-mortem radiological findings were correlated. The patient had a recurrence of this disorder in a subsequent pregnancy which was terminated at 15 weeks, supporting previous reports of an autosomal recessive inheritance pattern. The feasibility of diagnosing the following morphological features by prenatal ultrasonography is demonstrated: coronal clefts of the vertebral bodies, metaphyseal and epiphyseal abnormalities, spinal deviations such as cervical kyphosis and a horizontal sacrum, additional ossification centres in the pelvis, and preaxial deviation of the thumbs and toes. The differential diagnosis of this disorder from other skeletal dysplasias with similar features is discussed. 相似文献

This paper reports on successful prenatal diagnosis of X-linked anhidrotic ectodermal dysplasia (AED) by means of light and electron microscopy on fetal skin biopsies obtained under fetoscopy. In the present family two brothers of the proband were severely affected with the full symptomatology of AED, the pregnant female and her mother revealed minor symptoms with patches of skin lacking vellus hair. Control of lesional skin of the affected family members by electron microscopy revealed no ultrastructural abnormalities. However, all biopsies lacked skin appendages including hair follicles, sebaceous glands, and sweat glands. The lack of pilosebaceous follicles can be used as a diagnostic criterion since these structures are fully developed in normal fetuses of 20 weeks whereas the development of sweat glands does not start before week 20 to 24 of fetal life. Skin biopsies were taken from various regions of the fetus at risk via fetoscopy in week 20 and processed for light and electron microscopy. All samples revealed complete absence of all skin appendages in contrast to a total of 61 non-AED fetuses. Thus positive prenatal diagnosis of AED was made and the pregnancy was terminated. Control investigations after abortion confirmed the diagnosis. 相似文献

A case of thalidomide syndrome diagnosed by ultrasound in the 17th week of pregnancy is presented. The pregnant woman had leprosy and received adjuvant treatment with thalidomide. The affected fetus was exposed to the drug until the 35th day of pregnancy and presented absent external ears, upper limb phocomelia and absent tibiae and fibulae. No internal organ abnormalities were noticed at autopsy. 相似文献

Fetal gastroschisis is regarded as a relatively straightforward ultrasound diagnosis. We report two cases of infants born with undiagnosed gastroschisis despite several detailed prenatal assessments following raised serum alphafetoprotein measurements. In both cases, the bowel was healthy with no evidence of long-term herniation through the abdominal wall and primary surgical correction was successful. Gastroschisis has previously been classified as ‘antenatal’ and ‘perinatal’, and we conclude that the latter type is not always possible to diagnose prenatally. 相似文献

A 30-year-old woman had serial ultrasound scans from 28 weeks' gestation which revealed the presence of a cystic area in the fetal pelvis. The ‘cyst’ remained unchanged until delivery at 41 weeks. Fetal growth and amniotic fluid volume were normal throughout. A pelvic kidney was confirmed at birth. The differential diagnosis and antenatal management of this ‘cyst’ are discussed. 相似文献

Although malignant transformation of fetal cervical teratoma is extremely rare, perinatal morbidity is high and usually related to the size of the tumour, which may compromise fetal swallowing and subsequently lead to upper airway obstruction. We present a case in which mid-trimester serial sonography demonstrated markedly rapid early growth of a lesion of this type between 17 and 19 weeks' gestation indicating the aggressive nature of this tumour, assisting parental decision to terminate the pregnancy. Histopathology confirmed grade 3 immaturity of the lesion. 相似文献

Ultrasonography was performed during the second trimester (17 weeks) in a pregnancy at risk for osteogenesis imperfecta congenita (OI). The scan showed that the femur was short, bent and dense. Radiologic examination of the fetus after interruption of pregnancy showed typical X-ray changes of OI. 相似文献

The ultrasound findings in a series of 15 prenatally diagnosed cases of severe osteogenesis imperfecta types IIA, IIB, IIC, and III are described, eleven being detected on routine scans of women with no relevant history. As most cases of osteogenesis imperfecta type IIA are dominant sporadic mutations, the importance of prenatal diagnosis during routine scanning at a local level is emphasized. In addition to characteristic broad, shortened and fractured long bones, striking features of the chest and head are highlighted which may be encountered during a routine scan, prompting further assessment. 相似文献

Osteogenesis imperfecta (OI) Type II was diagnosed accurately in an at-risk fetus at 16 weeks gestation by real-time sonography. The most important findings were shortening, deformity and possibly fracture in the long bones particularly the femurs. Ultrasonic visualization of these signs in a fetus at risk will provide direct evidence in the diagnosis of OI Type II and any additional investigations are not indicated. 相似文献

The prenatal diagnosis of autosomal dominant polycystic kidney disease (ADPKD) is now being reported with increasing frequency. We report three cases and review 12 cases of ADPKD diagnosed in the fetus by ultrasonographic findings. Increased echogenicity and renal enlargement are the main ultrasonographic signs of ADPKD. Renal cysts are uncommon. Diagnosis is easy in a family with a positive ADPKD history. Conversely, there may be no apparent family history, as in our three cases and three cases from the literature. We consider the problems of unexpected diagnosis, family investigation, and the prognosis of ADPKD in children with prenatally diagnosable forms. 相似文献

In 3 fetuses affected by congenital chloride diarrhoea there were characteristic prenatal ultrasonic findings. In all cases the fetal abdominal cavity was filled with distended loops of fetal intestine, the fetal stomach was of normal size and polyhydramnios was present. The prenatal ultrasonic findings in this metabolic inherited disease are identical to those caused by mechanical obstruction of the distal fetal intestine. Whenever these findings are encountered prenatally, the possibility of chloride diarrhoea should be considered, because therapy with electrolytes is needed rather than the surgical intervention required in mechanical intestinal obstruction. 相似文献

Prenatal transvaginal diagnosis of the ectrodactyly,ectodermal dysplasia,cleft palate (EEC) syndrome
Transvaginal ultrasonography performed at 14 weeks' gestation demonstrated a bilateral cleft lip and lobster-claw deformities of the hands and feet, in keeping with the diagnosis of EEC syndrome (ectrodactyly or lobster-claw deformity, ectodermal dysplasia, and cleft lip and palate). The fetus was aborted and the diagnosis of EEC syndrome was confirmed. 相似文献

Prenatal diagnosis of a fetus at risk for hypochondroplasia, a short limb dwarfism condition similar to achondroplasia, was performed by ultrasound at 22 weeks' gestation. The limb bones were measured and shown to be decreased in length. The pregnancy was terminated. Post abortion X-ray did not show caudal narrowing in the lumbar spine but the pelvis had the features of hypochondroplasia. 相似文献

Arthrogryposis Multiplex Congenita (AMC) was suspected on ultrasound examination of a fetus at 30·5 weeks of gestation. The criteria for establishing this prenatal diagnosis as well as the importance of establishing the diagnosis at any gestational age are discussed. The diagnosis of AMC was confirmed at birth in this case. 相似文献
