This patient failed initial twice-surgical resections, central nervous system (CNS) irradiation, and adjuvant chemotherapies and high-dose thiotepa and melphalan with auto peripheral blood stem cell rescue. Finally, imatinib treatment was undergone as a palliative setting, however the tumor did not reduce and the patient died of tumor bleedings. We consider that the reasons for the failure are as follows: i) adequate CNS level of imatinib were not obtained because of the blood brain barrier, ii) the lack of plateletderived growth factor receptor beta expression in our case may have a crucial role. %K imatinib mesylate %K platelet derived growth factor receptor (PDGFR) alfa %K choroid plexus carcinoma. %U http://www.clinicsandpractice.org/index.php/cp/article/view/441
