Choroid plexus hyperplasia

Choroid plexus hyperplasia (CPH), also known as villous hypertrophy of the choroid plexus, is a rare benign condition that is characterized by bilateral enlargement of the entire choroid plexus in lateral ventricles without any discrete masses. This can result in overproduction of CSF and communicating hydrocephalus.


Histology shows increased number of normal-sized cells. 

Radiographic features
