title: Papillary tumor of the pineal region: report of a rapidly progressive tumor with possible multicentric origin.
abstract: Papillary tumor of the pineal region (PTPR) is an uncommon tumor recently added to the WHO classification of CNS tumors. We report a case of PTPR in a young boy that was noteworthy for early CSF dissemination and relentless progression. In spite of intensive chemotherapy and comprehensive radiotherapy, the boy died. The neuroimaging appearance is unique with possible multicentric origin of the tumor and intense uptake of (111)In-DTPA-pentetreotide.
