OBJECTIVE: The objective of this study was to apply quantitative magnetic resonance imaging to characterize absolute cerebrospinal fluid (CSF) development, as well as its relative development to fetal brain parenchyma in the healthy human fetus. DESIGN: We created three-dimensional high-resolution reconstructions of the developing brain for healthy fetuses between 18 and 40 weeks' gestation, segmented the parenchymal and CSF spaces, and calculated the volumes for the lateral, third, and fourth ventricles; extra-axial CSF space; and the cerebrum, cerebellum, and brainstem...

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...

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...

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...

AIM: To improve clinical/laboratory diagnosis of bacterial meningitis (BM) in children. MATERIAL AND METHODS: Fifty-seven patients, aged from 4 months to 12 years, with BM were examined. Bacteriological study of the mucus from the nasopharynx, sterility tests of blood and cerebrospinal fluid (CNF), clinical and biochemical tests, serological study of paired samples of plasma - indirect hemagglutination test, latex agglutination assay, immunological study of plasma and CNF with the determination of interferon -α, -β and -γ, interferon procalcitonin and neopterin with ELISA were performed at admission and after CNF remediation...

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. CASE REPORT: A 44-year-old female presented with painful neuropathy and weakness of the intrinsic hand muscles...

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...
