title: Papillary tumor of pineal region: prolonged control rate after gamma knife radiosurgery - a case report and review of literature.
abstract: Papillary tumors of the pineal region (PTPR) are very rare. We describe the first report of a PTPR empirically managed with gamma knife radiosurgery. The patient was initially shunted and referred for empirical gamma knife radiosurgery. After initially showing some improvement, he had recurrence of tumor after 7 years. For recurrence he underwent a gross total resection and the biopsy established the diagnosis of PTPR. Further research needs to be done as to the efficacy of gamma knife surgery for PTPR. In addition, the role of stereotactic biopsy for eligible patients should be considered as the initial step to direct the treatment of choice.
