Choroid plexus tumors are a rare type of cancer that occur from the brain tissue called choroid plexus of the brain.[3] Choroid plexus tumors are uncommon tumors of the central nervous system that account for 0.5–0.6% of intracranial neoplasms in people of all ages.[4][5] Choroid plexus papilloma, atypical choroid plexus papilloma, and choroid plexus carcinoma are the three World Health Organization types for these neoplasms.[6] Children under the age of five account for 10% of cases of choroid plexus tumors.[7] In children and adults, respectively, the lateral ventricle and the fourth ventricle are common locations,[8][9][10] About 5% of all choroid plexus tumors are located in the third ventricle.[11] Along with other unusual places such the cerebellopontine angle, the Luschka foramen, or brain parenchyma, the third ventricle is a rare location for choroid plexus tumors.[12][13][14][15] Together, atypical choroid plexus papilloma, and choroid plexus carcinoma make up around 25% of all choroid plexus tumors.[16] Although there have been reports of third ventricle choroid plexus papillomas in people in their fifth decade of life, only 14% of choroid plexus tumors are reported to arise in infants.[17][18] Most findings indicate that choroid plexus tumors have no sex predilection.[19][20]
