Choroid plexus hyperplasia

Choroid plexus hyperplasia (CPH), also known as villous hypertrophy of the choroid plexus, is a rare benign condition that is characterised 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.

Pathology

Histology shows increased number of normal-sized cells. 

Radiographic features

MRI

This is best diagnosed by MRI which demonstrates a diffuse enlargement and homogeneous enhancement of choroid plexuses in a patient with communicating hydrocephalus.
