An autopsy was performed in one case of metastatic spinal tumor with complete paralysis. Histopathological findings in the case were examined with a view to confirm the venous circulatoy disturbance in the spinal cord. The findings of the degenerative change to sponge and enlarged vein in the spinal cord showed circulatory disturbance in venous system. In addition to those findings, multicystic softening evidenced that the degenerative change of spinal cord was due to circulatory disturbance in venous system. Another finding of this case, diffuse infiltration of tumor cell was observed in the whole vertebral body (Th. IO-L. 3), so that we can't find normal vein in vertebral body. This finding suggests that the circulatory disturbance in venous system was caused by diffuse block of the flow from internal vertebral venous plexus to external vertebral venous plexus in vertebral body.
