在中枢神经系统,有一些部位解剖学上称为非神经区(或特殊区),包括延髓最后区(Area Postrema),穹窿下器官(Subfornicate organ)、丘脑下部灰结节(Tuber cinereum)、脉络丛(Choroid plexus)、脑垂体(Pituitary)和松果体(Pineal body)等。中枢神经系统发生白血病时,这些部位常出现白血病细胞浸润。多年来关于非神经区病变方面的研究资料很少,尤其是对病变发生的机制以及与其他部位病变的关系等,尚无统一意见。 In the central nervous system, some parts are anatomically referred to as non-neurological regions (or special regions), including Area Postrema, Subfornicate organ, Tuber cinereum, Choroid plexus, Pituitary and Pineal body and the like. Leukemia in the central nervous system, these parts often appear leukemia cell infiltration. For many years non-neurological lesions on the research data rarely, especially on the pathogenesis of lesions and other parts of the relationship between the disease, there is no uniform opinion.
