Choroid plexus tumours on MRI: similarities and distinctions in different grades

open access: yesCancer Imaging, 2019
Background The therapeutic planning varies for different grades of choroid plexus tumours (CPTs). The aim of this study was to define the similarities and distinctions among MRIs for different grades of CPTs, providing more guidance for clinical ...

Congenital Intracranial Tumors: Prenatal Diagnosis by Fetal Magnetic Resonance Imaging

open access: yesiRADIOLOGY, Volume 3, Issue 3, Page 203-208, June 2025.
Fetal intracranial tumors are rare, comprising 0.5%–1.9% of all childhood tumors, with their true incidence potentially underestimated. This review highlights the role of fetal MRI, particularly with advanced sequences, in diagnosing common fetal brain tumors such as teratomas, astrocytomas, and choroid plexus papillomas, often presenting unique ...

Culture models to study leukocyte trafficking across the choroid plexus

open access: yesFluids and Barriers of the CNS, 2013
Background A critical point during the course of central nervous system infection is the influx of leukocytes from the blood into the brain across the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB).

Imaging Assessment of the Pituitary Gland and Long‐Term Endocrinological Abnormalities in Pediatric Brain Cancer Survivors

open access: yesJournal of Magnetic Resonance Imaging, Volume 61, Issue 6, Page 2516-2522, June 2025.
Background Pediatric brain cancer survivors often experience hypothalamic–pituitary dysfunction due to cranial irradiation and chemotherapy. While hormone deficiencies have been studied, the changes in pituitary size and shape on long‐term MRI and their relationship to endocrine dysfunction remain under‐explored.

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced

Comparison of Echo Planar and Turbo Spin Echo Diffusion‐Weighted Imaging in Intraoperative MRI

open access: yesJournal of Magnetic Resonance Imaging, Volume 61, Issue 4, Page 1847-1857, April 2025.
Background Diffusion‐weighted imaging (DWI) is routinely used in brain tumor surgery guided by intraoperative MRI (IoMRI). However, conventional echo planar imaging DWI (EPI‐DWI) is susceptible to distortion and artifacts that affect image quality. Turbo spin echo DWI (TSE‐DWI) is an alternative technique with minimal spatial distortions that has the ...

Leptomeningeal Dissemination in Choroid Plexus Tumors: Magnetic Resonance Imaging Appearance and Risk Factors

open access: yesChildren
Background: Intracranial choroid plexus tumors (CPT) are rare and primarily affect young children. Leptomeningeal dissemination (LMD) has been reported not only in high-grade choroid plexus carcinoma (CPC) but also in lower histological grades; however ...

Transcallosal Removal of a Choroid Plexus Tumor From the Lateral Ventricle in a Dog. Case Report

open access: yesFrontiers in Veterinary Science, 2020
A 6-years-old female Staffordshire terrier was referred for periodic generalized seizures and asymmetric visual deficits. Magnetic resonance imaging revealed a 23.2 × 19.3 × 23.0 mm soft tissue mass within the right lateral ventricle and consequential ...

Primary Diffuse Leptomeningeal Melanomatosis Leading to Raised Intracranial Pressure in a Pediatric Patient

open access: yesClinical Case Reports, Volume 13, Issue 2, February 2025.
ABSTRACT A critical clinical consideration, in addition to other common risk factors predisposing individuals to idiopathic intracranial hypertension (IIH), involves the potential co‐occurrence of increased intracranial pressure and elevated cerebrospinal fluid protein levels in the presence of underlying malignancies.
