[Primary meningeal sarcomatosis of the brain and spinal cord with multiple tumor nodes]

One case of this rare tumor diagnosed clinically in a female of 24 is reported. Cell composition was the same in both brain and spinal cord. There was a combination of a diffuse pattern of tumor cell arrangement with a formation of nodules and the spread of tumour cells along the perivascular spaces into the brain and spinal cord, along the endoneurium to the cranial and spinal nerve roots and metastasizing through the liquor system.
