Conjoined twins have a rare prevalence and special curiosity among physicians and the general population. The reported frequency varies from 1:50,000 to 1:200,000 pregnancies. Its early diagnosis becomes very important when we think about pregnancy management, method of delivery and neonatal care. We describe two cases of conjoined twins diagnosed by ultrasound and magnetic resonance during prenatal care with the aim to better studying the fetus anatomy. The first conjoined twins were cephalopagus sharing head, thorax and abdominal wall and with two pelvis and four arms and four legs. The second were thoracopagus, united by thorax and part of abdomen. Magnetic resonance imaging contribution was not important to diagnose conjoined twins. However, it was useful to describe the shared organs, contributing to define fetal outcome.

Osteogenesis imperfecta is a connective tissue disorder due to quantitative and qualitative anomalies in type 1 collagen, genetically transmitted by a dominant or recessive autosomal gene, leading to bone fragility. We report a case of a 19-year-old G1 PO patient referred to our institution following a screening ultrasound that demonstrated short limb fetal extremities. A level 3 scan was performed which evidenced an irregular cranial shape and compression of the cephalic pole with moderate transducer pressure. Limb shortening, decreased echoes and fractures of long bones were found on our scan evaluation. A vaginal delivery occurred at 35 weeks of gestation. The male newborn, weighing 1.990 grams had 6 and 8 in Apgar scores. The neonate was clearly abnormal, presenting irregular cranial shape, with poor ossification on X-ray, blue sclera, fractures and limb deformities. Postnatal evaluation was satisfactory and the neonate was discharged in good conditions. Prenatal diagnosis is important for an adequate pregnancy follow-up. Postnatal outcome was not related to vaginal delivery, as there were no recent fractures in the newborn.

Congenital cytomegalovirus infection is an important clinical entity, due to its sonographic symptomatology. In Brazil, in utero diagnosis is not accomplished despite the improvements in diagnostic methods. We report a congenital infection including: splenomegaly and hepatomegaly, hypoplasia of the cerebellar vermis, intracranial calcifications, hyperechoic kidneys, hyperechoic bowel, cardiomegaly, lung hypoplasia, ascites, and pericardial effusion. Fetal magnetic resonance imaging confirmed the sonographic findings. Amniocentesis was performed for cytomegalovirus PCR in amniotic fluid, which confirmed fetal infection. Fetal loss occurred in the 31st week of pregnancy. Necropsy studies confirmed the sonographic findings. The diagnostic methods have been useful to confirm congenital cytomegalovirus infection and to establish fetal outcome.

Purpose: to determine the frequency of prenatal diagnosis in newborns with gastroschisis operated at the Instituto Materno-Infantil de Pernambuco (IMIP) and to analyze its repercussions on neonatal prognosis. Patients and Methods: a cross-sectional study was carried out, including 31 cases of gastroschisis submitted to surgical correction in our service from 1995 to 1999. Prevalence risk (PR) of neonatal death and its 95% confidence interval were calculated for the presence of prenatal diagnosis and other perinatal and surgical variables. Multiple logistic regression analysis was carried out to determine the adjusted risk of neonatal death. Results: only 10 of 31 cases of gastroschisis (32.3%) had prenatal diagnosis and all were delivered at IMIP. No newborn with prenatal diagnosis was preterm but 43% of those without prenatal diagnosis were premature (p < 0,05). Birth-to-surgery interval was significantly greater in the absence of prenatal diagnosis (7.7 versus 3.8 hours). The type of surgery, need of mechanical ventilation and frequency of postoperative infection were not different between the groups. Neonatal death was more frequent in the group without prenatal diagnosis (67%) than in the group with prenatal diagnosis (20%). The main factors associated with increased risk of neonatal death were gestational age <37 weeks, absence of prenatal diagnosis, delivery in other hospitals, birth-to-surgery interval > 4 hours, staged silo surgery, need of mechanical ventilation and postoperative infection. Conclusions: prenatal diagnosis was infrequent among infants with gastroschisis and neonatal death was extremely high in its absence. It is necessary to achieve greater rates of prenatal diagnosis and to improve perinatal care in order to reduce this increased mortality.
