The choroid plexus is located within the cerebral ventricles and is made of choroidal epithelial cells (type of ependymal cell), loose connective tissue (tela choroidea), and permeable capillaries. It produces cerebrospinal fluid.
the roof of the temporal horns of the lateral ventricles, extending along the floor of the body of the lateral ventricles, through the interventricular foramen of Monro, and along the roof of the third ventricle. They typically do not extend into the frontal or occipital horns of the lateral ventricles

Rich in blood supply and lack of blood-brain barrier lead to avid enhancement of a normal choroid plexus after contrast administration. However, the enhancement may appear asymmetrical on both sides of the brain or mass-like, leading to false interpretations of tumor 4.
On the other hand, choroid plexus can be entirely calcified and lack enhancement which can resemble other types of non-enhancing tumors such as tuberculoma, neurocysticercorsis, non-enhancing meningioma or schwannoma 4.
