Using Manganese‐Enhanced DCE‐MRI to Assess Blood‐Cerebrospinal Fluid Barrier Transport

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2083-2091, November 2026.
ABSTRACT PurposeWe developed a dynamic, heavily T2‐weighted (hT2w) FLAIR protocol to resolve acute Mn2+ transport kinetics, as a proxy for Ca2+, across the choroid plexus (ChP)—cerebrospinal fluid (CSF) interface, in vivo. By quantifying intercompartmental Mn2+ dynamics, and comparing these with Gd‐DOTA, we sought to characterize blood‐CSF‐barrier ...

A Benign Giant Fibroblastic Intraventricular Meningioma: A Rare Case Report with Review of Literature

Medical Journal of Dr. D.Y. Patil Vidyapeeth
Intraventricular meningiomas are uncommon neoplasms and account for only 0.5 to 3%. They are seen mostly in the age group of 12 to 14 years. They arise from the arachnoid cap cells located in the choroid plexus.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, Volume 36, Issue 6, November 2026.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Atypical Ectopic Choroid Plexus Papilloma - Not so Benign

, 2019
Choroid plexus papillomas (CPP) are rare neoplasms (0.4-0.6% of all brain tumors) arising from cuboidal epithelial cells of the choroid plexus. We describe an adult with a rare atypical ectopic choroid plexus papilloma in the cerebellopontine angle with ...

Platelet-derived growth factor receptor expression and activation in choroid plexus tumors

, 2009
Choroid plexus tumors are intraventricular neoplasms predominantly affecting young children. In contrast to choroid plexus papillomas, choroid plexus carcinomas progress frequently, necessitating the development of adjuvant treatment concepts.

Methylation profiling of choroid plexus tumors reveals 3 clinically distinct subgroups [PDF]

, 2018
BACKGROUND: Choroid plexus tumors are intraventricular neoplasms derived from the choroid plexus epithelium. A better knowledge of molecular factors involved in choroid plexus tumor biology may aid in identifying patients at risk for recurrence. METHODS:
