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 role of adjuvant treatment in atypical choroid plexus papillomas is the subject of the most controversy in this regard. [ 32 ] [ 33 ] [ 34 ] When a tumor cannot be surgically removed, the best course of treatment is a neuroendoscopic biopsy followed by chemotherapy and radiation.
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 ...
Treatment is often largely dependent on the type of cyst. Asymptomatic cysts, termed pseudocysts , normally require active monitoring with periodic scans for future growth. [ 7 ] Symptomatic (producing or showing symptoms) cysts may require surgical removal if they are present in areas where brain damage is unavoidable, or if they produce ...
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 ...
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]
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 .
