The authors present a retrospective analysis of the results of the cytological examinations of cerebrospinal fluid (CSF) samples and tumor-cyst aspirates deriving from 262 patients treated for malignant intracranial primary and secondary tumors, and vertebral and peridural metastastic processes. Positive preoperative CSF samples were found in 15.3% of all cases of primary cerebral malignancies (13.9% of all gliomas) and positive postoperative CSF samples were found in 40% (91% of the medulloblastoma cases). In all cases of single or multiple secondary cerebral tumors, positive preoperative CSF samples were found in 20%.
