[Contribution to central nervous system tumor diagnosis by means of cytocentrifuged cerebrospinal fluid]

The cytocentrifugation of the liquor cerebrospinalis provides a useful diagnostic tool to differentiate benign from malign diseases of the central nervous system. The method is illustrated with liquor analyses in the field of pediatric oncology: medulloblastoma, leptomeninx sarcoma, plexuspapilloma, astrocytoma, Abt-Letterer-Siwe, ALL, reticulum cell sarcoma, Ewing sarcoma, retinoblastoma. The speed and ease of the processing, the highest possible cellular yield and the good preservation of the cellular characteristics are great advantages of this new method.
