Choroid plexus papilloma is a rare benign tumor originating from the epithelial cells of the choroid plexus, which often occurs in children, and can cause symptoms such as hydrocephalus, which can lead to increased intracranial pressure as well as limited neurological damage. Clinical manifestations include apathy, lethargy, headache, vomiting, and edema of the optic nerve papilla, and even unsteady walking, nystagmus, and epilepsy. The diagnosis can be confirmed by checking ct and magnetic resonance, and once diagnosed, craniotomy should be carried out in time to remove the tumor, which can be cured in general.
