CHOROID PLEXUS CYSTS
Choroid plexus cysts (CPCs) are nonneoplastic epithelial-lined cysts of the choroid plexus. They are the most common of all intracranial neuroepithelial cysts, occurring in up to 50% of autopsy cases. Most are bilateral and located in the lateral ventricular atria. The third ventricle is a rare but reported location (1). Most CPCs are asymptomatic and are found incidentally, typically in neonates and older adults. Symptomatic lesions are rare since the atria typically enlarge to accommodate the cyst
