Choroid plexus cysts (CPCs) are cysts that occur within choroid plexus of the brain. They are the most common type of intraventricular cyst, [1] occurring in 1% of all pregnancies. [2] It is believed that many adults have one or more tiny CPCs. [3] The fetal brain may create these cysts as a normal part of development.
During fetal development, some choroid plexus cysts may form. These fluid-filled cysts can be detected by a detailed second trimester ultrasound. The finding is relatively common, with a prevalence of ~1%. Choroid plexus cysts are usually an isolated finding. [18] The cysts typically disappear later during pregnancy, and are usually harmless.
The most common intracranial anomaly is the presence of choroid plexus cysts, which are pockets of fluid on the brain. These are not problematic in themselves, but their presence may be a marker for trisomy 18. [9] [10] Sometimes, excess amniotic fluid or polyhydramnios is exhibited. [7]
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
These classification of cysts are embedded in the endoderm (inner layer) and the ectoderm (outer layer) of the cranial or spinal cord germ layers.They normally take over the neuraxis, the axis of the central nervous system that determines how the nervous system is placed, which allows the cysts to infiltrate the CNS tissues.

Choroid plexus tumors are a rare type of cancer that occur from the brain tissue called choroid plexus of the brain. [3] Choroid plexus tumors are uncommon tumors of the central nervous system that account for 0.5–0.6% of intracranial neoplasms in people of all ages.
Primary neuronal tumors occurring in the ventricular system were considered to be rare. Most cases described were of non-neuronal origin such as oligodendroglioma, ependymoma, meningioma, choroid plexus papilloma and giant cell. Neurocytomas were probably historically misdiagnosed as intraventricular oligondedronglioma or clear cell ependymoma ...
In the case of choroid plexus papilloma, surgical removal of the cyst-containing lesion from within the third ventricle caused a full recovery. The mobile nature of the cystic lesion led to its intermittent obstruction of the foramen of Monro and proximal aqueduct, producing the bobble-head symptoms. Once removed, all symptoms disappeared.
