BackgroundPapillary tumor of the pineal region is an unusual, recently described entity with potential for misinterpretation as either an ependymoma or choroid plexus papilloma. With few reported cases, there is little data regarding the biologic behavior, natural course and optimal treatment for these patients. Further accumulation of reports will assist with defining this entity and may provide further insight into management of such patients.Case presentationThis patient was a 24-year-old male with new onset seizures and a decreased level of consciousness. MRI scan showed a large heterogeneously enhancing solid-cystic mass in the pineal region extending to the third ventricle.DiscussionPapillary tumor of the pineal region is a neuroepithelial tumor with distinct morphological and immunohistochemical features that can be utilized to help differentiate it from other primary and metastatic tumors occurring within this region. Although there is currently no clear consensus, the potential for disease progression and CSF dissemination supports early aggressive therapy in these patients.
