Neurological symptoms may result from the local accumulation of malignant cells in or near the brain (chloroma), infection, hemorrhage, or infarcts from leukostasis. Leukostasisis a syndrome that can include brain infarction due hyperviscosity of blood with vascular occlusion but CNS involvement is rarely encountered in adults.
