PURPOSE: Cognitive dysfunction is a major concern for children with brain tumors. A valid, user-friendly screening tool could facilitate prompt referral for comprehensive neuropsychological assessments and therefore early intervention. Applications of the pediatric perceived cognitive function item bank (pedsPCF) such as computerized adaptive testing can potentially serve as such a tool given its brevity and user-friendly nature. This study aimed to evaluate whether pedsPCF was a valid indicator of cerebral compromise using the criterion of structural brain changes indicated by leukoencephalopathy grades...

A recurrent glycine-to-arginine/valine alteration at codon 34 (G34R/V) within H3F3A, a gene that encodes the replication-independent histone variant H3.3, reportedly occurs exclusively in pediatric glioblastomas. However, the clinicopathological and biological significances of this mutation have not been completely elucidated; especially, no such data exist for tumor samples from Japanese patients. We analyzed 411 consecutive glioma cases representing patients of all ages. Our results demonstrated that 14 patients (3...

Hereditary Multiple Exostoses (HME) is a rare pediatric disorder caused by loss-of-function mutations in the genes encoding the heparan sulfate (HS)-synthesizing enzymes EXT1 or EXT2. HME is characterized by formation of cartilaginous outgrowths-called osteochondromas- next to the growth plates of many axial and appendicular skeletal elements. Surprisingly, it is not known whether such tumors also form in endochondral elements of the craniofacial skeleton. Here, we carried out a retrospective analysis of cervical spine MRI and CT scans from 50 consecutive HME patients that included cranial skeletal images...

BACKGROUND: Intramedullary hemangioblastomas are rare benign vascular tumors, infrequent in pediatric patients. Clinical symptoms vary according to the age of presentation, tumor size, location, and concomitant syringomyelia. This is the second reported case of hemangioblastoma presenting with acute hydrocephalus. CASE PRESENTATION: A 3-month-old infant with acute hydrocephalus was asymptomatic after a ventriculoperitoneal shunt was placed. She returned 3 months later with irritability, acute paraplegia, and respiratory distress...

BACKGROUND: Knowledge regarding the shape, size, and variability of the cricoid ring is important to properly choose the correct endotracheal tube (ETT) in the pediatric patient. Studies have measured the size of the cricoid ring using methodologies such as moulages, magnetic resonance imaging, and video-bronchoscopy. In the present study, computed tomography (CT) -based images were used to determine the shape, size, and configuration of the cricoid ring in the pediatric population taking into considerations growth and development...

Perturbations in the prefrontal cortex (PFC), hippocampus, and amygdala are implicated in the development of anxiety disorders. However, most structural neuroimaging studies of patients with anxiety disorders utilize adult samples, and the few studies in youths examine small samples, primarily with volume-based measures. This study tested the hypothesis that cortical thickness of PFC regions and gray matter volume of the hippocampus and amygdala differ between pediatric anxiety disorder patients and healthy volunteers (HVs)...

Pediatric spinal meningiomas are very rare. Most studies on pediatric spinal meningiomas are case reports with literature reviews. This study presented a surgical series of 14 pediatric patients with histologically proven sporadic spinal meningiomas, including 5 WHO grade II tumors. In this series, there were 9 male and 5 female patients with a mean age of 11.1 years. Seven tumors were located in the cervical spine, 5 in the thoracic spine, and 2 in the lumbar spine. Gross total resection (GTR) of the tumor with a well-demarcated dissection plane was achieved in 11 cases, subtotal resection was achieved in 2 cases, and partial resection was performed in 1 case...

Magnetic resonance imaging (MRI) is the workhorse modality in pediatric neuroimaging because it provides excellent soft-tissue contrast without ionizing radiation. Until recently, studies were uninterpretable without sedation; however, given development of shorter sequences, sequences that correct for motion, and studies showing the potentially deleterious effects of sedation on immature laboratory animals, it is prudent to minimize sedation when possible. This manuscript provides basic guidelines for performing pediatric neuro MRI without sedation by both modifying technical factors to reduce scan time and noise, and using a multi-disciplinary team to coordinate imaging with the patient's biorhythms...

Bone and joint pain are common causes of pediatric consultation for a variety of etiologies. The causes are mostly traumatic or infectious or have an inflammatory origin. Acute leukemia (AL) can sometimes begin with osteoarticular signs and radiological investigations such as magnetic resonance imaging (MRI) can help guide the diagnosis. We report on two cases of pediatric AL revealed by osteoarticular signs, with MRI helpful in the diagnostic procedure. In these children, the first signs were recurrent joint pain, with no blood count anomalies...

BACKGROUND: Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). OBJECTIVE: To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms...

The use of illicit drugs is currently a major medical problem among adolescents. Several illicit drugs have a high abuse potential and can be neurotoxic causing high morbidity and mortality. The clinical manifestation of adolescents with acute drug-induced neurotoxicity is often characterized by non-specific symptoms and findings. Early diagnosis is important to prevent death and permanent long-term neurological impairments. We report on clinical and neuroimaging findings in five adolescents with acute brain imaging following illicit drug intoxication to highlight the role of neuroimaging findings in the diagnostic work-up of pediatric acute drug-induced neurotoxicity...

Each year millions of young children undergo procedures requiring sedation or general anesthesia. An increasing proportion of the anesthetics used are provided to optimize diagnostic imaging studies such as magnetic resonance imaging. Concern regarding the neurotoxicity of sedatives and anesthetics has prompted the US Food and Drug Administration to change labeling of anesthetics and sedative agents warning against repeated or prolonged exposure in young children. This review aims to summarize the risk of anesthesia in children with an emphasis on anesthetic-related neurotoxicity, acknowledge the value of pediatric neuroimaging, and address this call for conversation...

BACKGROUND: Intrauterine infection is a significant cause of early preterm birth. We have developed a fetal-neonatal model in the rhesus macaque to determine the impact of chronic intrauterine infection with Ureaplasma parvum on early neonatal reflexes and brain development. METHODS: Time-mated, pregnant rhesus macaques were randomized to be inoculated with U. parvum (serovar 1; 10(5)cfu) or control media at ~120 dGA. Neonates were delivered by elective hysterotomy at 135-147 dGA (term=167d) stabilized and cared for in our nonhuman primate neonatal intensive care unit...

Over the past 15 years, functional near-infrared spectroscopy (fNIRS) has emerged as a powerful technology for studying the developing brain. Diffuse Optical Tomography (DOT) is an extension of fNIRS that combines hemodynamic information from dense optical sensor arrays over a wide field of view. Using image reconstruction techniques, DOT can provide images of the hemodynamic correlates to neural function that are comparable to those produced by functional MRI (fMRI). This review article explains the principles of DOT, and highlights the growing literature on the use of DOT in the study of healthy development of the infant brain, and the study of novel pathophysiology in infants with brain injury...

In this review article, we focus on the most recent applications of nuclear medicine techniques (mainly (99m)Tc/(111)In white blood cells (WBC) scan, [(18)F]-FDG-PET/CT, [(18)F]-FDG-PET/MRI, and (99m)Tc-IL-2 scintigraphy) in the study of children affected by peripheral bone osteomyelitis, fungal infections, inflammatory bowel diseases, and type 1 diabetes, owing to recent important published evidences of their role in the management of these diseases. For osteomyelitis in children, both bone scintigraphy and [(18)F]-FDG-PET have a major advantage of assessing the whole body in one imaging session to confirm or exclude multifocal involvement, whereas WBC scan has a limited role...

In the context of ante-natally diagnosed hydronephrosis, the vast majority of children with a dilated renal pelvis do not need any surgical treatment, as the dilatation resolves spontaneously with time. Slow drainage demonstrated at Tc-99m-mercaptoacetyltriglycine (MAG3) renography does not necessarily mean obstruction. Obstruction is defined as resistance to urinary outflow with urinary stasis at the level of the pelvic-ureteric junction (PUJ) which, if left untreated, will damage the kidney. Unfortunately this definition is retrospective and not clinically helpful...
