Cerebrospinal fluids (CSF) of 44 patients with cryptococcosis associated with Acquired Immunodeficiency Syndrome (AIDS), treated in the Ward XI of the Muñiz Hospital from January 2000 to December 2004, were retrospectively analyzed. The physical, chemical, cytological and mycological characteristics of CSF obtained by lumbar puncture at the moment of admission were taken into account in each case. India ink microscopy was positive in 38 (90.5%) out of 42 patients and the remainning 6 patients were diagnos- ed by cultures and/or determination of capsular antigen of Cryptococcus neoformans. At physical examination, 29 (69%) out of 42 samples showed a limpid aspect and the remaining 13 were hemorrhagic (n=3), opalescent (n=6), xanthochromic (n=3) or turbid (n=1). Chemically, the median of proteinorraquia was 0.7 g/L (range 0.1-3.5 g/L), 38 g/L (range 12-75 g/L) for glycorrhachia and 127 meq/L (range 130-143 mEq/L) for clorurorrachia. The capsular antigen of Cryptococcus neoformans, available for 7 CSF and blood samples, showed a median of 1/1.000 in both, with higher values in blood than in CSF. The CSF of patients with AIDS associated cryptococcosis evaluated in the present study did not reveal important differences, at least in the evaluated parameters, with respect to those cited in the literature.
