Tehran University of Medical Sciences Acta Medica Iranica 0044-6025 43 2 2005 04 15 158 160 G. R. Zamani M. Mohammadi 2015 09 28 Choroid plexus papillomas are rare intracranial tumors, accounting for less than 1% of all intracranial tumors in adults. However, they are relatively more common in children and constitute 1.5 to 4% of childhood intracranial tumors. In children, choroid plexus papillomas are predominately located in the lateral ventricles, followed by the forth and third ventricles and, rarely, in the cerebellopontine angle. Bilateral choroid plexus papillomas of lateral ventricles are very rare and only afew cases have been reported. Here we report a 10 year old boy who was admitted for chronic headache and vomiting of 6 months duration. Brain imaging showed bilateral tumor in the lateral ventricles. The patient underwent surgery and histopathological study certified the diagnosis of choroid plexus papilloma. https://acta.tums.ac.ir/index.php/acta/article/view/2984 https://acta.tums.ac.ir/index.php/acta/article/download/2984/2965
