[Morphogenesis of neuroleukemia]

A comparative study of neuroleukemia in children with acute leukemia and in mice with experimental leukemia was carried out. Spontaneous leukemia in AKR mice and transplantation leukemia (LIO-I, La, P388, L-5178Y) were shown to be adequate models for investigations on the pathogenesis of neuroleukemia. The initial morphological manifestations of neuroleukemia consisted in infiltration of dura mater of the brain and epidural space, particularly of the lumbar region of the spine. The leukemic cell infiltrates originating from the bone marrow spread along the walls of vascular anastomoses between the venous system of the skull and vertebrae on the one hand, and dura mater of the brain and epidural space of the spinal cord, on the other.
