abstract: A cytomorphological study of the cerebrospinal fluid corresponding to 42 patients with tumors of the central nervous system has been performed. The group of 31 patients with primary tumors accounted for an overall cytological positivity of 32.2 percent; according to the type of tumor cytological positivities were as follows: glioblastoma multiforme (44.4 percent); grade I/III astrocytoma (33.3 percent); oligodendroglioma (33.3 percent); ependymoma (25 percent), and meningioma (16.6 percent). In the group of 11 patients with metastatic tumors, neoplastic cells were observed in two cases (cytological positivity 18.1 percent). Cytological study of the cerebrospinal fluid is a useful diagnostic method for some primary and secondary neoplasms of the central nervous system.
