What is Choroid Plexus?

Choroid is derived from the Greek word ‘choroids’ which means skin-like. The choroid plexus, also known as the “plica choroidea,” is a collection of specialised cells that surround a capillary and border the membrane of the pia mater and ventricles. It is involved in neuro-endocrine, neuro-immune, and excretory functions. Choroid plexus produces cerebrospinal fluid (CSF), a clear fluid that cushions the brain and spinal cord, provides nutrients, and removes waste products. The choroid plexus consists of a rich blood supply and epithelial cells that actively transport substances into and out of the cerebrospinal fluid, contributing to the brain’s overall homeostasis and function....

Choroid Plexus Location

The choroid plexus is located within the brain’s ventricles, specifically in the lateral, third, and fourth ventricles of the human brain. It is found in the frontal or occipital horn of the lateral ventricles and the cerebral aqueduct. Choroid plexus is a capillary-rich membrane that runs along a portion of the ventricles’ inner layer and it only exists in the central nervous system....

Choroid Plexus Cyst

Choroid plexus cysts are fluid-filled sacs that develop within the choroid plexus. These cysts are usually benign and often asymptomatic, meaning they do not cause noticeable symptoms. Choroid plexus cysts typically form during fetal development, often appearing in the second trimester of pregnancy. They are commonly detected during prenatal ultrasounds or brain imaging scans. While they usually do not require treatment and tend to resolve on their own, monitoring may be recommended in certain cases, especially if there are concerns about associated conditions or complications. Choroid plexus cysts are generally considered a normal variant of brain development and are not associated with significant health risks....
