title: Extramedullary hematopoiesis in cerebellar hemangioblastoma.
abstract: Extramedullary hematopoiesis and paraneoplastic erythrocytosis are uncommon in cerebellar hemangioblastoma, and their concomitant occurrence has not been reported. In a study of 26 cases of hemangioblastoma, we found extramedullary hematopoiesis in 4 tumors; one was associated with erythrocytosis. The significance of this association and the possible histogenetic origin of extramedullary hematopoiesis in cerebellar hemangioblastoma are discussed.
