Klistorner S, Barnett MH, Wang C, Parratt J, Yiannikas C, Klistorner A. Longitudinal enlargement of choroid plexus is associated with chronic lesion expansion and neurodegeneration in RRMS patients.

Increased volume of the choroid plexus, which produces and secretes cerebrospinal fluid (CSF), was tied to cognitive impairment and Alzheimer's disease, a retrospective study showed. Among 532 ...

MRI processing steps. For volumetry (left), choroid plexus (CP) volume (red) and cerebral cortex volume (green) are segmented from T1-weighted volumetric images by using an automatic volumetric ...

Choroid plexus tumors can be either benign or malignant. In a 2024 analysis of over 600 people with these tumors from the years 2000 to 2019, over 70% of the tumors were benign, or noncancerous.

Increased volume of an important structure in the brain called the choroid plexus is linked to greater cognitive impairment and Alzheimer’s disease, according to a new study.

Choroid plexus tumors develop in the choroid plexus. They often form within the brain’s ventricles. They may also form in other areas of the central nervous system (CNS).
