  • Abstract
  • Look Inside

We tried to examine the growth pattern of meningeal gliomatosis (MG) by using an experimental MG model. C6 rat glioma cells (3 × 105/0.1 ml) were injected per-cutaneously into the cisterna magna of rats. Seven days after inoculation, the brains and spinal cords were re-moved and processed for morphological observation.

Light microscopic findings showed that numerous tumor cells had invaded the spinal cord parenchyma directly and/or via the Virchow-Robin spaces. In con-trast, a small amount of tumor cells had spread horizon-tally on the surface of the spinal cord.
