Callosal Dysgenesis

Intracranial lipomas are uncommon benign lesions of the central nervous system. Intracranial lipomas are usually asymptomatic and an occasional finding. They are frequently associated with more severe congenital anomalies like corpus callosum agenesis, and may present with seizures, headache, and behavioral disturbances. The MRI techniques are superior to CT and US in terms of exact anatomical localization of the lesions, and the origin of the lipoma and its relationship to surrounding structures. .

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.

The paper shows the limits restricting traditional histological methods when studying the white matter of the central nervous system on the example of corpus callosum. The study resulted in obtaining fundamentally new information concerning corpus callosum structure on the microscopic level of its organization. It became possible due to the first applied methods of brain tissue plastination in epoxy resin followed by further making of thin sections and series of half-thin slices.

Cns Anomalies

Introduction: Approximately 21% of congenital anomalies (CA) involve the Central Nervous System (CNS), constituting one of the most common birth defects, affecting 1 to 10: 1,000 of live births. Objective: To analyze the prevalence of CNS anomalies diagnosed by obstetric ultrasound. Methods: Prospective longitudinal cohort study carried out in a public fetal medicine service in Goiânia with pregnant women who were attended in high-risk prenatal care. The patients were followed up during the ultrasound exams from March 2018 to March 2019. Results: 225 cases of pregnant women with ultrasound diagnoses of CA were surveyed during the investigated period. CNS anomalies were the most prevalent, being present in 34.22% (77/225) of the cases. The mean maternal age of pregnant women was 25.55 years and mean gestational age was 28.84 weeks. Hydrocephalus was identified in 23 pregnant women (29.87%), being the most prevalent CNS anomalie. Anencephaly was present in 24.68% (19/77) and holoprosencephaly in 18.18% (14/77). Other CA were also diagnosed (21/77), such as meningocele, spina bifida, acrania, among others. However, they showed a lower prevalence in relation to hydrocephalus, anencephaly and holoprosencephaly. Conclusion: The findings are essential for the planning and allocation of hospital resources and investment in health. Besides that, to adequate and specific prenatal care, is indispensable in the search for reducing the incidence of these malformations, morbidity and improving survival rates of the affected population.

Neurenteric cysts are rare benign lesions of the central nervous system that are lined by endodermal cell–derived epithelium. Although they occur mostly in the spine, they can occur intracranially, most often in the posterior fossa. Neurenteric cysts that are located in the anterior cervicomedullary junction are even rarer and often require a skull base approach for adequate resection. The authors describe two cases of neurenteric cysts arising from the cervicomedullary junction that were resected via a far-lateral transcondylar approach. They discuss the surgical approach and operative nuances involved in removing these lesions, and review the clinical presentation of neurenteric cysts in this region as well as the neuroimaging characteristics, histopathological findings, and surgical management. Intraoperative videos are presented.

Velum Interpositum

AbstractPineal region tumors are uncommon among neoplasm of the central nervous system, with this region being the most heterogeneous in terms of histological types. Meningiomas are rarer still, but can be found at this site, with origins in either the velum interpositum or falcotentorial junction. Neuroimaging exams can distinguish malignant from benign lesions besides helping to define the origin of the lesion as the pineal parenchymal or surrounding structures. We report the case of a woman with a pineal region tumor in which differential diagnoses included meningioma and germinoma, with confirmation of the former based on radiological characteristics and histopathology. In addition, a brief review of differential diagnoses and approaches for cases of lesions in this region is provided.
