Some authors believe that the cerebral form is caused by aberrant worms migration to the vertebral venous plexus (Batson plexus), producing eggs directly in the CNS (8).
Since the veins are valveless, the Batson plexus is thought to allow migration of tumor cells into the vertebral plexus when the intra-abdominal pressure is increased, even in physiologic situations such as moving from the supine to the sitting and standing positions.[7] The vertebral venous complex forms innumerable anastomoses with the sinusoidal structure of the vertebral bone marrow and the epidural venous channels.
It is unclear if the Batson plexus plays a role in generating these micrometastases.
