各种类型的白血病可在中枢神经系统造成损害,其途径为:(一)白血病细胞直接浸润神经组织,造成破坏和出血。(二)白血病续发血液凝血机制障碍引起颅内出血。(三)慢性淋巴细胞白血病可併发一种多灶性白质脑病损害大脑机能据Schwab和weiss统计,临床上显示出神经受累的病人,约占全部白血病病人的25～50%。尸解发现的数字更高,可达80%左右。对于神经内外科医师来说,这是一个很值得重视的问题。 Various types of leukemia can cause damage in the central nervous system by: (A) leukemia cells directly infiltrating nerve tissue, causing damage and bleeding. (B) leukemia sequelae of blood clotting mechanism caused by intracranial hemorrhage. (C) of chronic lymphocytic leukemia can be complicated by a multifocal leukoencephalopathy damage to brain function According to Schwab and weiss statistics, the clinical manifestations of nerve involvement of patients, accounting for about 25 to 50% of all leukemia patients. The number of autopsy found higher, up to 80%. This is a problem worth attention to neurosurgeons.
