Pineal region tumors are rare comprising 0.4% to 0.1% of all primary tumors of the central nervous system^1,2 and constitute 3% to 11% of childhood brain tumors.^3-5 These tumors are classified into tumors of germ cell origin, which clearly account for the majority of tumors in this region and those originating from pineal parenchymal cells.¹ The latter include pineoblastomas, pineocytomas, and tumors of glial origin. These retain the potential for neuronal or glial differentiation.^1,6 Approximately three-fourths of tumors in this area are malignant with the propensity for seeding(3,7,8,9,10). Retrospectively we have analyzed 47 cases of pineal region tumors and have discussed the clinical features, histopathology, management and outcome.
