The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. [1] Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nervous system. [2] [3] The choroid plexus consists of modified ependymal cells surrounding a core of ...
In children and adults, respectively, the lateral ventricle and the fourth ventricle are common locations, [8] [9] [10] About 5% of all choroid plexus tumors are located in the third ventricle. [11] Along with other unusual places such the cerebellopontine angle, the Luschka foramen, or brain parenchyma, the third ventricle is a rare location ...
Choroid plexus papilloma, also known as papilloma of the choroid plexus, is a rare benign neuroepithelial intraventricular WHO grade I lesion found in the choroid plexus. [1] It leads to increased cerebrospinal fluid production, thus causing increased intracranial pressure and hydrocephalus .
The brain contains pockets or spaces called ventricles with a spongy layer of cells and blood vessels called the choroid plexus. This is in the middle of the fetal brain. The choroid plexus has the important function of producing cerebrospinal fluid. The fluid produced by the cells of the choroid plexus fills the ventricles and then flows ...
A choroid plexus carcinoma (WHO grade III) is a type of choroid plexus tumor [1] that affects the choroid plexus of the brain. It is considered the worst of the three grades of chord plexus tumors, having a much poorer prognosis than choroid atypical plexus papilloma (WHO grade II) and choroid plexus papilloma (WHO grade I). [2]
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialized ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. In humans, there is about 125 mL of CSF at any one time ...
For example, cerebrovascular disease involves brain injury due to problems with the blood vessels (cardiovascular system) supplying the brain; autoimmune disorders involve damage caused by the body's own immune system; lysosomal storage diseases such as Niemann–Pick disease can lead to neurological deterioration
Chordoma is a rare slow-growing neoplasm thought to arise from cellular remnants of the notochord.The evidence for this is the location of the tumors (along the neuraxis), the similar immunohistochemical staining patterns, and the demonstration that notochordal cells are preferentially left behind in the clivus and sacrococcygeal regions when the remainder of the notochord regresses during ...
