Atypical choroid plexus papilloma (ACPP) and choroid plexus carcinoma (CPC) are both primary brain tumors that begin near the brain tissue. Choroid plexus carcinoma is fast-growing high-grade tumor, whereas atypical choroid plexus papilloma is an intermediate-grade tumor.
Removing these tumors through surgery has the best outcome for patients with ACPP or CPC, but there are often complications that can occur during the surgery.
