The majority of pineal gland tumors present at least by the third decade of life. Thus, other diagnosis should be entertained in pineal tumors occurring in older adults. Metastasis to pineal gland has been reported with low frequency.[7] Pineoblastomas can rarely occur in late adulthood.[8] Pineoblastomas are also composed of poorly differentiated discohesive cells with scanty cytoplasm and pleomorphic nuclei but unlike lymphomas they may exhibit nuclear molding, rosette formation and are negative for immunomarkers of lymphoma. Diagnostic work-up of a patient presenting with pineal gland mass includes serum tumor marker studies of germ cell tumors. Stereotactic biopsy of the pineal gland is recommended if the tumor marker levels are normal. Our patient was treated with RTOG protocol and is doing well.
