Ectopic choroid plexus papilloma

Asian Journal of Neurosurgery, 2018
Choroid plexus papilloma is a rare intracranial neoplasm. These lesions most commonly present in the fourth ventricle in adults and lateral ventricle in children. Herein, we report a case of a 57-year-old male with complaint of backache of few weeks duration. Magnetic resonance imaging revealed an intradural and extramedullary space occupying lesion at

Relationships Between Lateral Ventricle Size, Cerebrospinal Fluid Dynamics, and Aqueductal Resistance in Young Healthy Adults

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Ventricular enlargement and abnormal cerebrospinal fluid (CSF) circulation are closely associated in communicating hydrocephalus (NPH), yet their causal relationship remains unclear. Studying healthy populations may help clarify these mechanisms.

T2‐Weighted T1 Mapping and Automated Segmentation of CSF: Assessment of Solute Gradients in the Healthy Brain

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

Mapping Intracellular Volume Fraction With Susceptibility Source Decomposition as a Marker for Tissue Cellularity

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Pathophysiological changes affect tissue cell composition and density. For example, neurodegenerative disorders and brain tumors are associated with cell loss and abnormal accumulation, respectively. In these scenarios, if monitored and tracked, tissue cellularity might be used to inform clinical diagnosis and management. Purpose To

Diagnostic dilemma of cystic biliary atresia: A series of two cases and brief review of the diagnostic modalities

JPGN Reports, EarlyView.
Abstract Cystic biliary atresia (CBA) is a rare variant of biliary atresia that closely resembles choledochal cyst (CC), complicating diagnosis and potentially delaying critical surgical intervention. We report two cases of CBA that were difficult to diagnose.

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

The Lipidome of the Lateral Ventricle Choroid Plexus Exhibits Sex-Specific Changes Across Aging. [PDF]

J Neurochem
As we age, the brain's fluid‐producing tissue—the choroid plexus—undergoes changes in its fat composition. Using advanced lipid analysis in mice, we discovered that these changes differ between males and females and may influence brain inflammation and barrier function. Our findings highlight that maintaining lipid balance in this tissue is crucial for
