Fetal cerebral ventriculomegaly (VM) is diagnosed when the width of one or both ventricles, measured at the level of the glomus of the choroid plexus (atrium), is ≥ 10 mm. VM can result from different processes: abnormal turnover of the cerebrospinal fluid (CSF), neuronal migration disorders, and destructive processes. In a high percentage of cases, it is associated with structural malformations of the central nervous system (CNS), but also of other organs and systems. The rate of associated malformations is higher (≥60%) in severe VM (>15 mm) and lower (10–50%) in cases of borderline VM (10–15 mm). When malformations are not present, aneuploidies are found in 3–15% of borderline VM; the percentage is lower in severe VM. The neurodevelopmental outcome of isolated VM is normal in > 90% of cases if the measurement of ventricular width is between 10 and 12 mm; it is less favorable when the measurement is > 12 mm.

With increasing use of fetal ultrasound comes an increase in the detection of clinically silent ‘abnormalities’ which pose diagnostic and management dilemmas for perinatologists and paediatricians. Congenital thoracic malformations (CTMs) (excluding congenital diaphragmatic hernia) are one such example, where a few cases are symptomatic in early life and management options are clear, but the majority are clinically asymptomatic, giving rise to difficulties in defining postnatal management of the well child with a sonographic or radiological lesion. Here, we will outline the prenatal presentation and natural history of CTMs that are not congenital diaphragmatic herniae and briefly discuss the approach to postnatal management, which is covered in more detail in the review by Laje and Liechty in this issue.

Congenital splenic cyst (CSC) is a rare condition, and only a few cases with prenatal diagnosis and no associated malformation have been reported. Spontaneous regression is possible in case of mild CSC (under 40 mm), but enlargement or secondary complications may lead to surgical treatment. We report, herein, two cases of isolated mild CSC with complete spontaneous postnatal regression. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Diaphragmatic eventration is the upward displacement of the abdominal viscera secondary to a thin or paralytic diaphragm. Its clinical presentations and radiographic pictures are similar to those of diaphragmatic hernia. Prenatal diagnosis of diaphragmatic eventration is extremely rare. A pregnant woman was referred to us because of abnormal cardiac findings noted at 20 weeks of gestation. A diagnosis of partial anomalous pulmonary venous connection was made on the basis of our findings of right atrial enlargement with an abnormal vascular channel drainage to it. The infant was born via cesarean section at 40 weeks and developed complications of cyanosis immediately after birth. Postnatal imaging studies and surgical findings disclosed right side diaphragmatic eventration with liver and associated vasculature upward displacement into the right pleural cavity. The cardiac structure was otherwise normal. We conclude that when an abnormal vessel tracing and unexplainable cardiac chamber asymmetry is encountered, diaphragmatic eventration should be considered as one of the differential diagnoses. Correct recognition and transferral to the hospital for neonatal assistance may lead to timely and appropriate management of these fetuses. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Although congenital mesoblastic nephroma (CMN) is a rare benign congenital renal tumor, it is the most common solid renal tumor in the newborn period. The most common presentation of congenital mesoblastic nephroma is polyhydramnios, and only one case with prenatal fetal hydrops has been previously reported. Prenatal diagnosis of CMN has previously been made on the basis of the findings of sonography in the third trimester, and magnetic resonance imaging (MRI)–based diagnosis has been reported recently. Here we report a case of prenatally diagnosed classical type CMN diagnosed at 22 + 3 weeks of gestation based on the findings of sonography and magnetic resonance imaging. The characteristic imaging findings in this case were fetal hydrops and polyhydramnios. To our knowledge, this is the youngest reported gestational age for prenatal diagnosis of CMN and it is the second case of CMN associated with fetal hydrops detected prenatally.
