BACKGROUND: Neonatal sonography of the brain is now an essential part of newborn care, particularly in high risk and unstable premature infants. Cranial ultrasound is the most available and easily repeatable imaging technique for the neonatal brain showing brain development and the most frequently occurring forms of cerebral injury in the preterm and terms. This study aims to assess the importance of cranial ultrasound as an investigatory modality for high-risk neonates and to find out the morphology of various cerebral lesions and correlate clinically...

INTRODUCTION: A considerable increase of imported Zika virus (ZIKV) infection has been reported in Europe in the last year. This is the result of the large outbreak of the disease in the Americas, along with the increase in the numbers of travellers and immigrants arriving from ZIKV endemic areas. METHODS: A descriptive study was conducted in the Tropical Medicine Unit of Hospital La Paz-Carlos III in Madrid on travellers returning from an endemic area for ZIKV from January to April 2016...

OBJECTIVE: To evaluate the acquisition-related factors influencing the quality of the brain volumes for further study of advanced neurosonography. METHODS: This was a prospective multicentre study. Five centres were asked to include five cases each, acquiring two volumes per case, at different gestational ages. Ten operators performed an advanced neurosonography per case. The potential influence of the following factors on the number of evaluable structures was assessed: vaginal/ abdominal acquisition, position of the head, gestational age, subjective quality of the volume and the acquiring operator itself...

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...

INTRODUCTION: The additional value of peripheral nerve ultrasound in acquired immune-mediated neuropathies has recently been reported. Its impact in vasculitic neuropathy is yet to be defined. We report electrophysiological and nerve ultrasound studies in a patient with nonsystemic vasculitic neuropathy at first diagnosis and in response to immunosuppression.

BACKGROUND: Supracondylar humerus fractures are very common in pediatric populations. In cases of dislocated fractures, closed reduction and percutaneous K‑wire fixation is recommended. Initially, 10-16 % of the patients also present lesion of the ulnar nerve as well as median nerve palsy in 6.4% and radial nerve palsy in 2.6 % of cases, respectively. METHOD: We present the case of a 10-year-old boy with a dislocation of the elbow and fracture of the medial epicondyle...

UNLABELLED: A total of 48 patients undergoing surgical decompression of the ulnar nerve at the cubital tunnel between February 2010 and May 2013 were retrospectively studied to determine changes in the cross-sectional area of the nerve by the technique of neurosonography. The mean follow-up was 46 months. Post-operative follow-up examination of the cross-sectional area of the ulnar nerve showed a slight reduction in the mean value from 13.8 mm(2) (pre-operative) to 12.9 mm(2) (post-operative)...

PURPOSE: To evaluate the additional diagnostic value of fetal Magnetic Resonance Imaging (MRI) in fetuses with suspected brain abnormalities identified with advanced neurosonography (NS). METHODS: A systematic literature search was performed for studies reporting on a comparison between diagnosis with NS and MRI, in fetuses suspected for brain abnormalities. Abnormalities detected on NS were compared with those detected on MRI as well as with postnatal imaging findings to assess the added value of fetal MRI...

PURPOSE: The objective of this study was to prenatally detect corpus callosum pathologies such as agenesis, partial agenesis, hypo- and hyperplasia and enhanced echogenicity. MATERIALS AND METHODS: Between 2009 and 2013 detailed 3D ultrasound examinations of the fetal corpus callosum were carried out as part of a level III examination for fetal anomalies. All scans were performed using Voluson E8 equipment (GE, Zipf, Austria) with a 5 - 8 MHz 3D transabdominal and 5 - 9 MHz 3D transvaginal transducer...

REVIEW
Alan Daneman, Monica Epelman
This article emphasizes technical factors that are helpful for optimizing sonographic examinations of the brain in preterm and term neonates. It also reviews existing data regarding the accuracy of neurosonographic examinations relative to MR. Many neurosonographic signs are subtle and can be easily overlooked, which could lead to delayed diagnosis or misdiagnosis. Therefore meticulous attention to sonographic technique is required to maximize the diagnostic utility of this modality. Although MR images of the brain often depict abnormalities more clearly than sonography, neurosonography continues to be an exceptionally valuable tool for evaluation of the neonatal brain, even in full-term neonates...

OBJECTIVE: The aim of this research was to determine the prevalence and sonographic appearance of the hippocampal commissure in fetuses with isolated complete agenesis of the corpus callosum by three-dimensional neurosonography in the multiplanar mode. METHODS: This was a multicenter observational study. Stored volume datasets of fetuses with isolated complete agenesis of the corpus were retrospectively retrieved for analysis in three tertiary centers. The presence or absence of the hippocampal commissure was independently evaluated in the coronal and midsagittal planes by two operators...

Purpose: The clinical use of detailed fetal neurosonography has increased over the past decade. This retrospective study explored the spectrum and frequency of different forms of corpus callosum anomalies (CCAs) in a level III center setting. Materials and Methods: Between 1999 and 2012, 48 907 detailed second and third trimester scans were performed. Among them, 140 (0.29 %) cases of CCA were diagnosed. We differentiated between complete and partial agenesis, hypoplastic corpus callosum (CC) and isolated and non-isolated forms...

The parasagittal (PS) plane is a 2-D diagnostic plane used routinely in cranial ultrasonography of the neonatal brain. This paper develops a novel approach to find the PS plane in a 3-D fetal ultrasound scan to allow image-based biomarkers to be tracked from prebirth through the first weeks of postbirth life. We propose an accurate plane-finding solution based on regression forests (RF). The method initially localizes the fetal brain and its midline automatically. The midline on several axial slices is used to detect the midsagittal plane, which is used as a constraint in the proposed RF framework to detect the PS plane...

PURPOSE: The aims of this study were to describe a new ultrasonographic technique to assess the normal level of the cerebellum and the brainstem in the posterior fossa in normal foetuses and to compare in pathologic cases. METHODS: We propose a new line cross between the dens cervical and the inferior portion of occipitum (occipitum-dens line-ODL). In a cross-sectional study, a single observer with experience in foetal neurosonography evaluated 54 foetuses (40 normal and 14 with open neural tube defect) between 20 and 28 weeks of gestation...

Intraoperative ultrasonography (IOUS) is a widely used noninvasive method to evaluate the morphology, vasculature, and pathologies of the brain. The advantages of IOUS include realtime depiction of neuroanatomy, accurate localization and characterization of a lesion, reduced surgical exploration and surgical time, and presumably decreased patient morbidity. IOUS is useful in the intraoperative monitoring of lesion resection as well as intraoperative localization and characterization of focal parenchymal lesions...
