The actual problem of modern obstetrics is a preterm delivery (PD), its tactics as the matter of specialists' discussions. One of the main components of "preterm delivery considerate management" is the conduction of fetus neuroprotection. Currently, the only wide spread preparation for fetus neuroprotection is magnesium sulphate, the advisability of that is criticized by several authors. The 62 neonatals of recurrent delivering women with monocarpous pregnancy, who delivered with 27-28- week gestation, were examined...

Fetal brain ultrasound remains as the mainstay for screening fetal intracranial anatomy. One of its main advantages is the availability of 3 dimensional and other ultrasound modalities for a better understanding of fetal neurodevelopment. Neurosonography is performed when findings, suggestive of an abnormality, are present on a screening ultrasound or if a high-risk situation of brain injury is present. This technique offers the use of complementary imaging planes, axial, coronal and sagittal, and the ability to image intracranial anatomy from the transabdominal and transvaginal approaches...

Lissencephaly is a severe malformation of cortical development, most often attributed to abnormalities in neuronal migration. It is associated with a severe prognosis including developmental delay, intellectual disability, and seizures. Lissencephaly can be reliably diagnosed during late gestation by neurosonography or fetal magnetic resonance imaging (MRI). We report two sibling male fetuses who were diagnosed with delayed cortical sulcation highly suggestive of lissencephaly during late pregnancy. After receiving genetic counseling, the parents elected to terminate the pregnancies based on the neuroradiological findings and the associated severe prognosis...

OBJECTIVE: To evaluate the impact of combined exposure to intra-amniotic inflammation and neonatal respiratory distress syndrome (RDS) on the development of intraventricular hemorrhage (IVH) in preterm neonates. METHODS: This retrospective cohort study includes 207 consecutive preterm births (24.0-33.0 weeks of gestation). Intra-amniotic inflammation was defined as an amniotic fluid matrix metalloproteinase-8 concentration >23 ng/mL. According to McMenamin's classification, IVH was defined as grade II or higher when detected by neurosonography within the first weeks of life...

OBJECTIVE: To describe the prenatal imaging features enabling diagnosis of developmental venous anomalies (DVA). METHODS: Four fetuses with unexplained persistent echogenic parenchymal brain lesions were studied. The evaluation included dedicated neurosonography, fetal MRI, serology for intrauterine infection, screening for coagulation abnormalities, and chromosomal microarray. Postnatal neurodevelopmental follow-up or autopsy results were assessed. RESULTS: DVA presented as very slowly growing echogenic brain lesions without cystic components, calcifications, or structural changes on otherwise normal neurosonographic scans performed at 2- to 3-week intervals...

Stuart Campbell was the first to use the metaphor of the parallel universes discussing the utilization of ultrasound in pregnancy.(1) The controversy around the use of magnetic resonance imaging (MRI) versus sonography to diagnose cerebral malformations is just another example in this regard. In one spatio-temporal continuum fetal neurosonography allows an accurate diagnosis of central nervous system anatomy(2-5) and malformations (6-9) including complex lesions such as commissural anomalies (10, 11) , posterior fossa malformations (12, 13) , disruptions (14-16) , and cortical anomalies(17) ; it performs similarly to magnetic resonance in the second and third trimester(18, 19) ; eventually, it allows a precise diagnosis of many malformations since the first trimester...

Neurosonography is a promising technique for prenatal diagnosis, combining features of ultrasound imaging with fetal neurology. The brain is a three-dimensional structure, therefore observing brain structure in the three basic planes (sagittal, coronal and axial) is mandatory. The anterior fontanelle and sagittal suture may serve as acoustic ultrasound windows in the transvaginal brain scan, allowing to obtain high-resolution neuroimages of the intracranial structures. Furthermore, three-dimensional (3D) ultrasound combined with the transvaginal brain approach provides detailed and sophisticated neuroimages...

Brain lesions and malformations have been described on ultrasonography of prenatal Zika infection; however, there are scarce reports about fetal magnetic resonance (MR) findings. We report 3 cases of fetuses with confirmed intrauterine Zika virus infection evaluated by ultrasound and fetal MR. Various morphometric measurements were assessed and brain maturation was calculated with the fetal total maturation score. Fetuses with prenatal Zika virus infection showed retardation in brain maturation indexes evaluated by fetal MR...

CLINICAL/METHODICAL ISSUE: Traumatic lesions of peripheral nerves and the brachial plexus are feared complications because they frequently result in severe functional impairment. The prognosis is greatly dependent on the correct early diagnosis and the right choice of treatment regimen. It is important to distinguish between open and closed injuries. STANDARD RADIOLOGICAL METHODS: Initial imaging must critically evaluate or prove nerve continuity and is commonly achieved by high-resolution ultrasonography...

BACKGROUND/AIMS: Brain shift during the exposure of cranial lesions may reduce the accuracy of frameless stereotaxy. We describe a rapid, safe, and effective method to approach deep-seated brain lesions using real-time intraoperative ultrasound placement of a catheter to mark the dissection trajectory to the lesion. METHODS: With Institutional Review Board approval, we retrospectively reviewed the radiographic, pathologic, and intraoperative data of 11 pediatric patients who underwent excision of 12 lesions by means of this technique...

Brain pathology is an important cause of morbidity and mortality in neonates, especially in the premature population. While conventional two-dimensional neurosonography is traditionally used for screening, diagnosis and monitoring of brain disorders such as germinal matrix hemorrhage, periventricular leukomalacia and hydrocephalus, three-dimensional ultrasonography has gained popularity in a variety of clinical applications in recent years. Three-dimensional ultrasonography is not yet widely utilized in pediatric imaging but is a potentially powerful tool for evaluating the neonatal brain...

COMMENT
S Tercanli, F Prüfer
Both in routine diagnostics and detailed, highly specialized workups, major advances have been observed in many areas of ultrasound due to an increase in expertise and improved technology in recent years. This is particularly true in the case of fetal neurosonography 1 2 3 4. Malformations of the CNS together with fetal heart defects are among the most common congenital anomalies. From the embryonic phase to the late third trimester, the CNS undergoes extensive development and maturation processes. The diagnosis of CNS anomalies is therefore primarily dependent on the time at which the examination is performed and the experience of the examiner...

REVIEW
Tally Lerman-Sagie, Zvi Leibovitz
Abnormal fetal corticogenesis results in malformations of cortical development (MCD). Abnormal cell proliferation leads to microcephaly or megalencephaly, incomplete neuronal migration results in heterotopia and lissencephaly, neuronal overmigration manifests as cobblestone malformations, and anomalous postmigrational cortical organization is responsible for polymicrogyria and focal cortical dysplasias. MCD comprises various congenital brain disorders, caused by different genetic, infectious, or vascular etiologies and is associated with significant neurological morbidity...
