This is unlike most other pediatric tumors and adult tumors, in which the locations of the tumors is reversed. In children, brain tumors are usually found in the infratentorial region and in adults, brain tumors are usually found in the supratentorial space. The relationship is reversed for choroid plexus papillomas. Signs and symptomsSigns of the tumor resulting from increased intracranial pressure are present in 91% of patients, with vomiting, homonymous visual field defects and headache being the most common symptoms. Other symptoms are ear ringing and dizziness. PathophysiologyThe tumor is neuroectodermal in origin and similar in structure to a normal choroid plexus. They may be created by epithelial cells of the choroid plexus. TreatmentChoroid plexus papillomas are benign tumors that are usually cured by surgery; malignant progression has been rarely reported. EpidemiologyInternationally tumors of the choroid plexus are rare, accounting for 0.4-0.6% of all intracranial neoplasms. It most commonly affects young children under the age of 5 with a mean patient age of 5.2 years.
