Since you have already read about these, you know that they are a benign tumor that usually shows up in the ventricles of the brain. They very rarely transform into a malignant process.
However, even if a process is benign, it can still cause some problems. The main one with CPP is that it grows to a size to put pressure on the surrounding brain tissue, or that it causes disruption of the flow of the cerebrospinal fluid (CSF) through out the brain.
In these cases the tumor usually has to be surgically removed.
Discuss the finding with your surgeon the next time you see him/her. Try not to worry TOO much. It is a benign process. Discuss all of your options with the surgeon. Good luck.
