Abstract Background Malformations of the central nervous system (CNS) constitute the 2nd most common group of fetal pathologies, which can be reflected throughout the patient's life. Fetal ultrasound (US), together with fetal magnetic resonance imaging (MRI) are extremely important techniques for the diagnosis of CNS malformations. The objective of this work was to address fetal US and fetal MRI, as well as the benefits of its use in different CNS pathologies and to ascertain which of the techniques presents better results. Methods For this systematic literature review, a search was conducted using databases such as PubMed® and ScienceDirect®, Google Scholar, b-on digital library, in a 10-year period, 2010 to 2020. 60 references were used, which met the inclusion criteria, namely compliance with the defined timeframe and the theme of the work to be addressed. Results As for the results, fetal US is the first-line technique for fetal evaluation, and its objective is to detect possible fetal malformations early, while fetal MRI complements the information collected through fetal US. When there are cases of isolated ventriculomegaly and complete agenesis of the corpus callosum, fetal US can correctly assess the pathology. When it comes to pathologies such as dysgenesis of the corpus callosum and malformations of the posterior fossa, fetal MRI evaluates more effectively in comparison to fetal US. Conclusions In conclusions, to reduce the number of false positives, the techniques should be used together, thus providing a better diagnosis.

There is some controversy about the value of fetal MRI in prenatal diagnosis, and most of the studies examine its accuracy in central nervous system (CNS) pathology. The objective of this retrospective study was to assess the diagnostic accuracy and usefulness of fetal MRI in the prenatal diagnosis of central nervous system (CNS) pathology and non-CNS pathology. Patients referred to the Radiology Department between 2007 and 2018 for a fetal MRI after detection of an anomaly in the fetal ultrasound, a high-risk pregnancy, or an inconclusive fetal ultrasound (n = 623) were included in the study. Postnatal diagnosis was used to assess the diagnostic accuracy of MRI. Fetal MRI was considered to provide additional information over fetal ultrasound when findings of the fetal MRI were not detected in the fetal ultrasound or when established a pathological condition that was not detected in the fetal ultrasound. Fetal MRI provided useful information for the perinatal management and prognosis over fetal ultrasound when findings of the fetal MRI changed the postnatal prognosis, leaded to the decision to legally terminate the pregnancy, changed prenatal or postnatal follow-up, or helped in the planning of prenatal or postnatal treatment. Fetal MRI offered an accurate diagnosis in 97% of cases (compared to 90.4% of fetal ultrasound; p < 0.001 ). Concordance between fetal ultrasound and fetal MRI was 92.1%. Fetal MRI provided additional information over fetal ultrasound in 23.1% of cases. In 11.6% of cases, the information was useful for the perinatal management and prognosis. In 45 cases (7.2%), fetal MRI was the only accurate diagnosis. In conclusion, fetal MRI has a superior diagnostic accuracy, especially in CNS pathology, and provides additional useful information in CNS, thoracic, and abdominal pathology.

Edwards Syndrome

Trisomy 18 (Edwards' syndrome), a lethal chromosomal aberration, is the second most common autosomal trisomy with an incidence 1: 8000. The aim of this study is to evaluate the sonographic findings in fetuses with trisomy 18. In ten years period (2002-2012) we analyzed fetal blood samples for chromosome abnormalities. Samples were taken by cordocentesis and processed using standard techniques. Sixteen metaphase cells were analyzed for chromosomal constitution in each sample after tripsin-Giemsa banding. A retrospective review of the cytogenetic laboratory database identified all cases of trisomy 18 in ten years period. The prenatal sonographic studies in fetuses at 16 to 22 weeks' gestation, done before invasive testing for the karyotype were reviewed for anatomic findings. From 2100 samples of fetal blood analyzed for chromosomal abnormalities, there were 16 (0,8%) with complete trisomy 18. We found no mosaicism, or partial trisomy 18. The women that carried fetuses with trisomy 18 were 17 to 42 years of age. Four of them were above 35. From 16 fetuses with trisomy 18, 14 (87,5%) had some anomaly detected by ultrasound, and other two were tested because of advanced maternal age. The most common findings in trisomy 18 were intrauterine growth retardation, polyhidramnios and anomalies of central nervous system, in 29% respectively. Multiple anomalies, including central nervous system, hart and gastrointestinal system anomalies, were also frequent (21%). Therapeutic termination of pregnancy was done in all cases after genetic counseling. Screening for chromosomal abnormalities using ultrasound is at utmost importance in cases of nonhereditary aberrations. Detailed ultrasonographic examinations of fetuses will enable health care providers to form the appropriate management plan for each patient.

The Central Nervous System

The results of observations of the first 100 neonates at the University of Texas Health Science Center (Houston) who received magnetic resonance imaging of the central nervous system by means of a high-field image (1.5 T) are reported. All were assessed prospectively to be at risk for neurodevelopmental delay. This first report specifically addresses the appearance of primarily hemorrhagic intracranial lesions, including intraventricular hemorrhage (n = 28), and extracerebral lesions, which include 3 cases of venous sinus thrombosis (n = 20). The signal intensities of hemorrhage underwent a characteristic evolution with time with only minor variations in the study group. Magnetic resonance imaging detected direct evidence of hemorrhage for up to 2 months, but hemosiderin was detected as a late indicator of hemorrhage for up to 9 months. Magnetic resonance imaging was equal in benefit to head ultrasonography and computed tomography for the diagnosis of intraventricular hemorrhage, but magnetic resonance imaging was also able to approximate the time of onset of hemorrhage. Magnetic resonance imaging was superior for the evaluation of extracerebral hemorrhage; ultrasonography failed to detect any of these lesions and computed tomography detected only 3 of 7. Short-term neurological abnormality was assessed, but the ability of magnetic resonance imaging to predict long-term neurodevelopmental delay is unknown and is the subject of an ongoing project.

Abstract Some neurotropic enteroviruses hijack Trojan horse/raft commensal gut bacteria to render devastating biomimicking cryptic attacks on human/animal hosts. Such virus-microbe interactions manipulate hosts’ gut-brain axes with accompanying infection-cycle-optimizing central nervous system (CNS) disturbances, including severe neurodevelopmental, neuromotor, and neuropsychiatric conditions. Co-opted bacteria thus indirectly influence host health, development, behavior, and mind as possible “fair-weather-friend” symbionts, switching from commensal to context-dependent pathogen-like strategies benefiting gut-bacteria fitness.
