The study was designed to assess the prevalence of pregnancy and delivery associated risk factors in children suffering from neonatal or presumed periventricular venous infarction. Antenatal records and pregnancy outcome data were retrospectively assessed in children with presumed periventricular venous infarction (n = 43, born ≥36 gestational weeks) or neonatal periventricular venous infarction (n = 86, born <36 gestational weeks) and compared to a matched control group (n = 2168, ≥36 gestational weeks) from a prospective study. Children with presumed periventricular venous infarction had significantly more maternal bacterial infections compared to the control group (47% vs 20%, respectively, < .001), whereas no difference was found compared to the neonatal periventricular venous infarction group (49%, = .80). Mothers with bacterial infection in the presumed periventricular venous infarction group had significantly more often pyelonephritis compared to the control group (50% vs 3.4%, respectively, < .001). Our data show an increased risk for developing periventricular venous infarction in the case of maternal bacterial infections, especially between gestational weeks 21 and 31.

How I do it? Resection of left ventricular central neurocytoma via trans-sulcal approach.
Acta Neurochir (Wien)
August 2024
Department of Neurosurgery, National Center for Neurological Disorders, Huashan Hospital, Fudan University, Shanghai, 200040, China.
Background: The management of lateral ventricle tumors requires a balance between maximizing safe resection and preserving neurological function.
Method: The authors present a successful case of a left lateral ventricular central neurocytoma resection. The trans-superior frontal sulcus approach was employed, providing a safe corridor while minimizing damage to the surrounding neuroanatomy.
The role of MRI biomarkers in evaluation of symptomatic pineal cysts - a retrospective analysis.
Acta Neurochir (Wien)
August 2024
Neurosurgical Department, University Medicine Greifswald, Greifswald, Germany.
Background: Our aim was to determine whether the Apparent Diffusion Coefficient is able to predict the presence of a symptomatic pineal cyst by detecting cerebral edema.
Methods: We retrospectively analyzed MRIs of 45 patients with pineal cysts before and after resection and 51 patients without pineal cysts, comparing ADC values of thalamus, central, periventricular and subcortical white matter. Furthermore we evaluated cyst size and morphology and analyzed its correlation to ADC values in corresponding patients.
Regulation of brain fluid volumes and pressures: basic principles, intracranial hypertension, ventriculomegaly and hydrocephalus.
Fluids Barriers CNS
July 2024
Department of Pharmacology, Tennis Court Rd, Cambridge, CB2 1PD, UK.
The principles of cerebrospinal fluid (CSF) production, circulation and outflow and regulation of fluid volumes and pressures in the normal brain are summarised. Abnormalities in these aspects in intracranial hypertension, ventriculomegaly and hydrocephalus are discussed. The brain parenchyma has a cellular framework with interstitial fluid (ISF) in the intervening spaces.

Neuroradiology
October 2024
Department of Medical Imaging, Perth Children's Hospital, 15 Hospital Ave, Nedlands, WA, 6009, Australia.
Purpose: Infants undergoing CSF shunting procedures face a rare complication which we propose to rename "Widespread Haemorrhages in Infants Post-Shunting" (WHIPS) to better capture this unique phenomenon specific to infants undergoing CSF diversion. Our objective is to analyse the risk factors for WHIPS development and provide a detailed neuroradiological description of these haemorrhages.
Materials And Methods: A radiology information system (RIS) was searched using the search terms "shunt" and/or "catheter" and/or "drain" and/or "ventriculoperitoneal" and/or "VP" between September 2008 to January 2021 for patients < 12 months of age.
Location-based clinical and angiographic profile of brain arteriovenous malformations - a single-center observational study.

Article Synopsis
- - The study aims to describe the clinical and angiographic traits of brain arteriovenous malformations (bAVM) based on their specific locations, which are important for prognosis and treatment decisions.
- - Researchers analyzed data from 269 bAVM cases at a national referral hospital from 2010 to 2020, categorizing them into eight location groups: frontal, temporal, parieto-occipital, periventricular, deep, cerebellar, brainstem, and mixed.
- - Significant differences were found among the groups in various aspects including clinical presentation, size and density of the bAVM, and characteristics of blood vessels involved, leading to the development of location-specific profiles for these conditions.
