We report the case of a preterm of 27 weeks of gestation who developed posthemorrhagic ventricular dilatation associated to a complete thrombosis of the superior sagittal sinus, for its peculiar interest in clarifying the physiology of the cerebrospinal fluid (CSF) dynamics.The exact CSF volume that must be removed to improve cerebral...

Background: Various strategies have been proposed for the treatment of gelastic seizures due to hypothalamic hamartomas (HH), advancing from surgical removal techniques toward functional disconnection strategies. One of the most recent procedure is the Magnetic Resonance guided Laser Interstitial Thermal Therapy (MRg-LITT), which has...

Background: Moyamoya disease (MMD) is a cerebrovascular disorder characterized by the progressive occlusion of the supraclinoid internal carotid artery (ICA), resulting in the formation of an abnormal cerebral vascular network. When MMD occurs in association with an underlying medical condition, including some distinctive genetic disorders, it...

Moyamoya disease is a steno-occlusive cerebrovascular disease of unknown etiology involving the terminal portion of the internal carotid artery and the proximal portions of the anterior and middle cerebral arteries with associated collateral vascular network. When the vascular pattern is associated with a particular condition (e.g., Type 1...

Background: Proton therapy has proven to be effective and safe in the treatment of radioresistant skull base tumors such as chordomas. Thanks to the peculiar physical properties of the proton beam, radiation energy is delivered in a narrow space called the Bragg peak and the surrounding normal tissues receive a minimal amount of the radiation...

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...

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....

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...

The management of drug-resistant patients with focal epilepsy is often challenging. Surgery is recognised as a useful and effective treatment option. The identification of the epileptogenic zone relies on the integration of clinical, neurophysiological, and neuroimaging findings. The role of non-invasive functional neuroimaging techniques has...

Laser ablation for treatment of hypothalamic hamartoma (HH) is a minimally invasive and effective technique used to destroy hamartomatous tissue and disconnect it from the functioning brain. Currently, the gold standard to evaluate the amount of tissue being "burned" is the use of heat maps during the ablation procedure. However, these maps...

Background: The pathogenesis of punctuate white matter lesions (PWMLs), a mild form of white matter damage observed in preterm infants, is still a matter of debate. Susceptibility-weighted imaging (SWI) allows to differentiate PWMLs based on the presence (SWI+) or absence (SWI-) of hemosiderin, but little is known about the significance of this...

Purpose: The role of T2*-based MR imaging in intracranial germ cell tumors (GCTs) has not been fully elucidated. The aim of this study was to evaluate the susceptibility-weighted imaging (SWI) or T2* gradient echo (GRE) features of germinomas and non-germinomatous germ cell tumors (NGGCTs) in midline and off-midline locations. Methods: We...
