BACKGROUND: Empty sella is the neuroradiological or pathological finding of an apparently empty sella turcica containing no pituitary tissue. The prevalence of primary empty sella, i.e., empty sella without any discernible cause, is not precisely known; estimates range from 2% to 20%. Technical advances in neuroradiology have made empty sella an increasingly common incidental finding. It remains unclear whether, and to what extent, asymptomatic adult patients with an incidentally discovered empty sella should undergo diagnostic testing for hormonal disturbances...

BACKGROUND: Magnetic resonance imaging (MRI) is used for neuroradiologic evaluation of patients with idiopathic growth hormone deficiency (IGHD). OBJECTIVES: To compare pituitary height and morphology at MRI between patients with IGHD and controls. MATERIALS AND METHODS: This retrospective study was conducted in pediatric patients, 3 years-15 years old, who had had brain MRI with non-contrast-enhanced midsagittal T1-weighted images. These images were measured for pituitary height and morphology of the pituitary gland including shape, stalk and posterior pituitary bright spot was evaluated...

Antibodies against the myelin oligodendrocyte glycoprotein (MOG-Ab) can be detected in various pediatric acquired demyelinating syndromes (ADS). Here, we analyze the spectrum of neuroradiologic findings in children with MOG-Ab and a first demyelinating event. The cerebral and spinal MRI of 69 children with different ADS was assessed in regard to the distribution and characteristics of lesions. Children with acute disseminated encephalomyelitis (n = 36) or neuromyelitis optica spectrum disorder (n = 5) presented an imaging pattern characterized predominantly by poorly demarcated lesions with a wide supra- and infratentorial distribution...

Neurologic complications can occur with extracorporeal membrane oxygenation (ECMO) due to several factors. Prior studies identified neonates as having unique risk factors and neuroimaging findings post ECMO. The aim of this study is to describe brain magnetic resonance imaging findings of pediatric patients treated with ECMO. We conducted a retrospective study of nonneonatal pediatric patients who underwent a comprehensive brain magnetic resonance imaging after ECMO between January 2000 and July 2015. We identified 47 pediatric patients in the study cohort with a median age of 8 months (interquartile range 3-170 months) and a median ECMO run duration of 7...

Cerebrotendinous xanthomatosis (CTX) is a lipid storage disorder caused by defective sterol 27-hydroxylase activity. In spite of subtle clinical signs beginning from childhood, CTX is generally diagnosed lately. The aim of this study is to evaluate clinical, neuroradiological findings and therapy responses of pediatric CTX patients and raise awareness to early features of disease. Patients who were molecularly diagnosed as CTX before 18 years of age were included in study. Clinical, epidemiological, radiological and genotypic features of patients and chenodeoxycholic acid (CDCA) therapy responses were reviewed retrospectively...

BACKGROUND: The necessity of imaging for patients with craniosynostosis is controversial. Lambdoid synostosis is known to be associated with additional anomalies, but the role of imaging in this setting has not been established. The purpose of this study was to evaluate the impact of preoperative imaging on intraoperative and postoperative management among patients undergoing operative intervention for lambdoid craniosynostosis. METHODS: A retrospective review of patients undergoing cranial vault remodeling for lambdoid craniosynostosis between January 2006 and 2014 was conducted...

PURPOSE: The use of DSC-MR imaging in pediatric neuroradiology is gradually growing. However, the number of studies listed in the literature remains limited. We propose to assess the perfusion and permeability parameters in pediatric brain tumor grading. METHODS: Thirty children with a brain tumor having benefited from a DSC-MR perfusion sequence have been retrospectively explored. Relative CBF and CBV were computed on the ROI with the largest lesion coverage. Assessment of the lesion's permeability was also performed through the semi-quantitative PSR parameter and the K2 model-based parameter on the whole-lesion ROI and a reduced ROI drawn on the permeability maps...

INTRODUCTION: Functional MR imaging is increasingly being used for presurgical language assessment in the treatment of patients with brain tumors, epilepsy, vascular malformations, and other conditions. The inherent complexity of fMRI, which includes numerous processing steps and selective analyses, is compounded by institution-unique approaches to patient training, paradigm choice, and an eclectic array of postprocessing options from various vendors. Consequently, institutions perform fMRI in such markedly different manners that data sharing, comparison, and generalization of results are difficult...

BACKGROUND: Anti-N-methyl-D-aspartate receptor encephalitis is a rare autoimmune disease characterized by severe neurological and psychiatric symptoms and a difficult diagnosis. The disease is often secondary to a neoplastic lesion, seldom diagnosed years later. Psychiatric symptoms are prevalent in adults; neurologic symptoms are more evident in children, who typically present primarily with neurological symptoms. To the best of our knowledge, the association with juvenile idiopathic arthritis has not been described...

PURPOSE: Although influenza primarily affects the respiratory system, in some cases, it can cause severe neurological complications. Younger children are especially at risk. Pediatric literature is limited on the diagnosis, treatment, and prognosis of influenza-related neurological complications. The aim of the study was to evaluate children who suffered severe neurological manifestation as a result of seasonal influenza infection. METHODS: The medical records of 14 patients from six hospitals in different regions of the country were evaluated...

Therapy-related neurotoxicity greatly affects possibility of survival and quality of life of pediatric patients treated for cancer. Central nervous system (CNS) involvement is heterogeneous, varying from very mild and transient symptoms to extremely severe and debilitating, or even lethal syndromes. In this review, we will discuss the broad scenario of CNS complications and toxicities occurring during the treatment of pediatric patients receiving both chemotherapies and hematopoietic stem cell transplantation...

OBJECTIVE Sporadic meningiomas have been classified in many different ways. Radiographically, these lesions can be described as occurring in either typical or atypical locations. The purpose of this study was to determine if there are any histopathological differences between sporadic meningiomas that arise in these varying locations in children. METHODS The neuroimaging, histopathological findings, and clinical records in patients with sporadic pediatric meningiomas not associated with neurofibromatosis Type 2 or prior radiation therapy were retrospectively reviewed...

Anesthetic management of patients undergoing endovascular procedures for treating intracranial aneurysms or cerebrovascular malformations must consider a number of specific challenges, in addition to those associated with anesthesia for other specialties. In addition to maintenance of physiological stability, manipulation of systemic and cerebral hemodynamic parameters may be required to treat any sudden unexpected catastrophic neurological events. A multidisciplinary group including neuro- and pediatric anesthesiologists, interventional neuroradiologists, neurosurgeons, and a clinical methodologist contributed to this document...

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...
