Emin Fidan, Dana D Cummings, Mioara D Manole
OBJECTIVE: Cerebral infarction due to minor head injury is rare. Mineralizing angiopathy is considered a predisposing factor for lenticulostriate stroke after minor closed head injury. This entity is characterized by infarction of the basal ganglia and most often occurs in young children, from infancy to 2 years of age. Symptoms usually occur immediately after the injury. METHODS AND RESULTS: We present the case of a previously healthy 2-year-old female child presenting with right facial hemiparesis and aphasia, along with right arm and leg weakness that occurred immediately after a fall from the couch onto a carpeted floor...

Congenital and perinatal primary brain neoplasms are extremely rare. Brainstem neoplasms in the perinatal and neonatal period are typically of high-grade nature and have poor prognoses with survival rates of less than 2 years from diagnosis. Herein, we report an unusual case of congenital anaplastic oligodendroglioma that arose in the pons and was detected as diffuse pontine glioma on in utero imaging studies during prenatal evaluation at 26 weeks' gestation. A male infant was delivered at 36.4 weeks of gestation via Cesarean section who developed progressive dyspnea shortly after birth...

BACKGROUND: Pathogenic heterozygous variants in the ATP1A2 gene have most commonly been associated with familial hemiplegic migraine. However, a wide spectrum of phenotypes that include alternating hemiplegia of childhood and epilepsy have been described. PATIENT DESCRIPTION: We describe a boy who presented at age three months with a complex phenotype that included epilepsy, nonepileptic paroxysmal events, and recurrent hemiplegia. Magnetic resonance imaging demonstrated unilateral cortical edema during a severe episode of hemiplegia that was followed by a persistent mild hemiparesis...

The treatment of lymphatic malformations (LMs) represents a great clinical challenge. The present study reported on the treatment of 68 infants with cervical macrocystic LMs using surgical resection. The cases were retrospectively analyzed. All patients underwent pre-operative ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) examinations. The surgery was performed under general anesthesia with endotracheal intubation. Ultrasonograms showed that 24 cases were monolocular, 44 were multilocular, 16 had no echo, 20 had a uniform low-level echo and 32 had a non-uniform low-level echo...

Medulloblastoma (MB) is recognized as comprising four molecular subgroups with distinct transcriptional profiles, clinical features, and outcomes. Previous studies demonstrate that pediatric MBs present with subgroup-specific MRI manifestations. We hypothesized that combination of anatomical localization and conventional features based on MR imaging can predict these subgroups in adult MBs. MR Imaging manifestations of 125 adult patients with MB were analyzed retrospectively based on pre-operative MRI scans...

The objective of the present study was to characterize the muscle magnetic resonance imaging (MRI) features of a 1-year-old girl with merosin-deficient congenital muscular dystrophy type 1A (MDC1A). Beginning as an infant, this patient exhibited severe hypotonia and proximal weakness, as well as delays in developmental milestones. Her serum creatine kinase levels at 3 months, 8 months and 1 year were 2,959, 1,621 and 1,659 U/l, respectively. Brain MRI indicated symmetric, mild T1WI low, mild T2WI and FLAIR high radial patterns in the white matter of the Cornu posterius of the ventricular lateral...

Preterm birth disrupts and alters the complex developmental processes in the cerebral cortex. This disruption may be a contributing factor to widespread delay and cognitive difficulties in the preterm population. Diffusion-weighted magnetic resonance imaging (DW MRI) is a noninvasive imaging technique that makes inferences about cellular structures, at scales smaller than the imaging resolution. One established finding is that DW MRI shows a transient radial alignment in the preterm cortex. In this study, we quantify this maturational process with the "radiality index", a parameter that measures directional coherence, which we expect to change rapidly in the perinatal period...

OBJECTIVE Chondrodysplasia punctata (CDP), a rare skeletal dysplasia, can lead to cervical spine instability and deformity. However, an optimal neurosurgical intervention has yet to be established. Thus, a retrospective study was conducted to assess the efficacy of various surgical interventions for children with CDP. METHODS The authors retrospectively reviewed 9 cases of CDP in which cervical decompression with or without posterior fusion was performed between April 2007 and May 2016. Patient demographics, preoperative clinical conditions, radiographic findings, surgical procedures, and the postoperative course were analyzed in detail...

BACKGROUND: Studies in rodents provide compelling evidence that microorganisms inhabiting the gut influence neurodevelopment. In particular, experimental manipulations that alter intestinal microbiota impact exploratory and communicative behaviors and cognitive performance. In humans, the first years of life are a dynamic time in gut colonization and brain development, but little is known about the relationship between these two processes. METHODS: We tested whether microbial composition at 1 year of age is associated with cognitive outcomes using the Mullen Scales of Early Learning and with global and regional brain volumes using structural magnetic resonance imaging at 1 and 2 years of age...

AIMS: As awareness and frequency of tethered spinal cord (TSC) related to occult spinal dysraphism (OSD) has increased with magnetic resonance imaging (MRI), variability exists in its evaluation and management. Due to no published level I data, we summarize the current International Children's Continence Society (ICCS) recommendations for diagnosis and treatment of OSD. METHODS: Guidelines were formulated based on analysis of pertinent literature and consensus among authors...

Herein, we report a conceptually novel clinical case highlighting the diagnostic implications of excessive homozygosity and its correlation with brain MRI abnormalities in an infant with GA1. The case also points a need for an extra amount of caution to be exercised when evaluating patients with "negative exomes."

OBJECTIVE: To investigate whether fetal growth restriction (FGR) has an adverse effect on white matter development. METHODS: A total of 28 full-term small for gestational age (SGA) infants were enrolled as study subjects and 15 full-term appropriate for gestational age infants were enrolled as control group. Conventional head magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) were performed for all infants. The white matter was divided into 122 regions...

OBJECTIVE: The infant temperament behavioral inhibition is a potent risk factor for development of an anxiety disorder. It is difficult to predict risk for behavioral inhibition at birth, however, and the neural underpinnings are poorly understood. The authors hypothesized that neonatal functional connectivity of the ventral attention network is related to behavioral inhibition at age 2 years beyond sociodemographic and familial factors. This hypothesis is supported by the ventral attention network's role in attention to novelty, a key feature of behavioral inhibition...

BACKGROUND: Neurological outcomes in neonatal hypoxic-ischemic encephalopathy (HIE) continue to be sub-optimal despite therapeutic hypothermia (TH). Cerebral near-infrared spectroscopy provides real-time regional oxygen saturation (CrSO2) that may be a marker of adverse MRI findings and neurodevelopmental outcomes. AIM: The aim of this study was to examine the value of CrSO2 monitoring in infants with HIE undergoing TH. STUDY DESIGN AND SUBJECTS: In this prospective study, CrSO2 was continuously recorded in 21 infants with HIE admitted for TH...

Alexander Disease (AD) is an autosomal dominant leukodystrophy and occurs predominantly in infants and children. It usually results in death within ten years after onset. Among the four subtypes, infantile form comprises the most of affected individuals. It presents in the first two years of life, typically with progressive psychomotor deficiency, loss of developmental milestones, seizures, and pyramidal signs. Clinical and magnetic resonance image findings usually establish diagnosis of AD. Here, we present a case of Infantile AD with characteristic clinical and radiological features...

BACKGROUND: Congenital cytomegalovirus (cCMV) infection is an important cause of hearing loss and neurodevelopment delay. While data on vertical transmission and neonatal outcome after singleton pregnancy with cCMV is well established, only scarce reports have addressed cCMV in multiple birth pregnancies. Furthermore, no studies have yet compared the outcome after birth and long-term follow up of children with cCMV born after a singleton vs. multiple pregnancy. METHODS: Infant outcome after birth of symptomatic vs...

Despite substantial progress in neonatal care over the past two decades leading to improved survival of extremely premature infants, extreme prematurity continues to be associated with long term neurodevelopmental impairments. Cerebral white matter injury is the predominant form of insult in preterm brain leading to adverse neurological consequences. Such brain injury pattern and unfavorable neurologic sequelae is commonly encountered in premature infants exposed to systemic inflammatory states such as clinical or culture proven sepsis with or without evidence of meningitis, prolonged mechanical ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis and chorioamnionitis...

BACKGROUND: Despite the increased recognition of cerebellar injury in survivors of preterm birth, the neurodevelopmental consequences of isolated cerebellar injury have been largely unexplored and our current understanding of the functional deficits requires further attention in order to translate knowledge to best practices. Preterm infants are exposed to multiple stressors during their postnatal development including perinatal cerebellar haemorrhage (CBH) and postnatal infection, two major risk factors for neurodevelopmental impairments...

BACKGROUND: Maternal inflammation during pregnancy increases the risk for offspring psychiatric disorders and other adverse long-term health outcomes. The influence of inflammation on the developing fetal brain is hypothesized as one potential mechanism but has not been examined in humans. METHODS: Participants were adult women (N = 86) who were recruited during early pregnancy and whose offspring were born after 34 weeks' gestation. A biological indicator of maternal inflammation (interleukin-6) that has been shown to influence fetal brain development in animal models was quantified serially in early, mid-, and late pregnancy...

  Kawasaki disease (KD) is a systemic vasculitis in infants. In KD, encephalopathy is rarely (0.1%) associated, however, clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) has previously been reported in some pediatric patients. Here, we report on a 2-year-old girl who had KD complicated with MERS. The patient experienced generalized clonic convulsion and prolonged consciousness disturbance with fever for 2 days. Her head MRI showed a high signal intensity lesion in the splenium of the corpus callosum in diffusion-weighted images, and low apparent diffusion coefficient (ADC) values on day 3...
