We report the case of a 13-year-old patient, female, born in Northern Italy, who presented with an acute episode of aphasia, lasting about 15 min, accompanied by left arm dysesthesia. The state of consciousness remained preserved throughout the episode. After a first clinical evaluation at second-level hospital, the patient was sent to our...

ULK4 and BRWD3 deletions have been identified in patients with developmental/language delay and intellectual disability. Both genes play pivotal roles in brain development. In particular, ULK4 encodes serine/threonine kinases that are critical for the development and function of the nervous system, while BRWD3 plays a crucial role in...

Background Spontaneous or idiopathic intramedullary bleeding is a very rare event in pediatric patients. This diagnosis requires an extended clinical, laboratory, and radiologic work-up to rule out all potential causes of hematomyelia. However, children may present with hematomyelia or spinal cord injury without radiographic abnormality even...

The purpose of the present study was to compare visual function assessment, visual evoked potential, and optical coherence tomography with measurement of retinal nerve fiber layer thickness for the diagnosis of optic pathway glioma in children with neurofibromatosis type 1.

Purpose In moyamoya vasculopathy, prolonged arterial transit time may increase the arterial spin labeling (ASL) signal heterogeneity, which can be quantitatively expressed by the spatial coefficient of variation of ASL-CBF (ASL-sCoV). The aim was to compare the accuracy of ASL-sCoV and ASL-CBF with dynamic susceptibility contrast (DSC)-CBF and...

Interstitial 6p25.1p24.3 microdeletions are rare events and a clear karyotype/phenotype correlation has not yet been determined. In this study, we present the clinical and molecular description of a child with a de novo 6p25.1p24.3 microdeletion, characterized by array-CGH, associated with mild intellectual disability, facial dysmorphisms,...

KIF5C encodes a protein belonging to the kinesin family and involved in cellular transport. Variants in KIF5C were first associated a decade ago with microcephaly and malformations of cortical development, with a phenotypic spectrum ranging from polymicrogyria to pachygyria. Currently, eight patients have been reported so far. Here we describe...

Background: Germinal matrix-intraventricular hemorrhage (GMH-IVH) is a common form of intracranial hemorrhage occurring in preterm neonates that may affect normal brain development. Although the primary lesion is easily identified on MRI by the presence of blood products, its exact extent may not be recognizable with conventional sequences....

Leigh syndrome (LS) is an early-onset progressive neurodegenerative disorder, characterized by a wide clinical and genetic heterogeneity, and is the most frequent disorder of mitochondrial energy production in children. Beside its great variability in clinical, biochemical, and genetic features, LS is pathologically uniformly characterized by...

Background: Epilepsy, ataxia, sensorineural deafness, and tubulopathy (EAST syndrome) is a rare channelopathy due to KCNJ10 mutations. So far, only mild cerebellar hypoplasia and/or dentate nuclei abnormalities have been reported as major neuroimaging findings in these patients. Methods: We analyzed the clinical and brain MRI features of two...

Background: Heterozygous POLR2A variants have been recently reported in patients with a neurodevelopmental syndrome characterized by profound infantile-onset hypotonia. POLR2A encodes the highly conserved RBP1 protein, an essential subunit of the DNA-dependent RNA polymerase II. Case presentation: We investigated a 12-year-old girl presenting...
