WebAug 5, 2013 · Specific Imaging Findings. Neuroepithelial cysts appear as well-circumscribed, ovoid, nonenhancing masses that follow CSF density/signal intensity. They can be of variable size and occur virtually anywhere, sometimes with a multiloculated appearance. No surrounding hyperintense gliosis is observed on FLAIR images. WebChoroid plexus cysts are most frequently located in the trigones of the lateral ventricles, but can occur throughout the ventricular system. They are typically less than 1 cm in diameter and are round or ovoid in shape. On CT, choroid plexus cysts usually demonstrate CSF density but can occasionally appear hyperdense relative to the CSF.
