We present here a case of fore-lying of the umbilical cord. In this case, transvaginal sonography did not reveal the umbilical cord beyond the fetal head before maternal urination; however, 5 minute later, a fore-lying umbilical cord was revealed between the floating fetal head and the uterine cervix after urination. The present case indicates the importance of careful evaluation of preterm pre...

Abbreviations AMI, automated multiplanar imaging; 3D; 3-dimensional; 2D, 2-dimensional nlike computed tomography and magnetic resonance imaging, ultrasonography is an operator-dependent imaging modality. Two-dimensional (2D) ultrasonographic images are obtained by manual positioning of the transducer, and the quality of such images is dependent on the technical skills and expertise of the sonog...

Sacrococcygeal teratoma is a congenital tumour, which may present in the prenatal period or at birth. The case presented illustrated one of the complications of sacrococcygeal teratoma, which is tumour rupture at birth. Other complications include fetal hydrops, fetal hydronephrosis, cervical dystocia, bleeding and death. Currently, diagnosis of sacrococcygeal teratoma is made during the prenat...

Congenital high airway obstruction syndrome (CHAOS) is the obstruction of the fetal upper airways, which may be partial or complete. It is usually incompatible with life. Prenatal recognition of the disease is quite important due to the recently described management options. We report here two cases of CHAOS due to tracheal atresia diagnosed by antenatal ultrasonography and fetal MRI. We also b...

The majority of pregnant women in the U.S. undergo prenatal ultrasonography and approximately 0.5% of these examinations will detect fetal malformations. Up to one-half of these abnormalities include the genitourinary system and the most common urological finding is hydronephrosis. Some conditions associated with prenatal hydronephrosis portend a poor prognosis, while others can follow a fairly...

OBJECTIVE To examine the diagnostic accuracy of clinical examination to determine fetal presentation in late pregnancy. DESIGN Cross sectional analytic study with index test of clinical examination and reference standard of ultrasonography. SETTING Antenatal clinic in tertiary obstetric hospital in Sydney, Australia. PARTICIPANTS 1633 women with a singleton pregnancy between 35 and 37 wee...

A 28-year-old woman at 32 weeks of gestation was referred to us for evaluation of a fetal mediastinal cystic mass detected during prenatal ultrasonography. MRI revealed a fluid-filled tubular structure extending from the carina along the presumed course of the fetal esophagus (Fig. A and B, arrows), polyhydramnios, and right pleural effusion (Fig. B, arrowhead). The diagnosis of esophageal dupl...

Objective To describe the prenatal diagnosis of Galen vein aneurysm (GVA) based on ultrasonography and magnetic resonance imaging (MRI) in a series of cases, as well as its postnatal outcomes and follow-up until 4 years of age. Methods A retrospective longitudinal study was performed, analyzing a database comprising seven cases of prenatal diagnosis of GVA at two Brazilian institutions from Feb...

Fetal goiter is an uncommon, serious problem during pregnancy. Careful routine antenatal ultrasound screening can find out an intrauterine fetal goiter. Fetal goiter has an incidence of 1:40000 live births (1). 80% of cases are caused by dysgenesis of the thyroid gland. The rest 5% and 15% are due to hypothalamohypophyseal abnormalities and dyshormonogenesis, respectively. 8% of cases are due t...
