Granulomatous mycoses of the central nervous system

A clinical and pathological description of five cases of granulomatous mycoses of the C.N.S. is reported. Four had an intracranial and one a spinal localization. In all patients the clinical pattern was of tumoral type, while the disease evolution was favourable only in one case. From a histipatholic point of view the preliminary diagnosis was of granulomatous process. The fungi organisms were identified only by means of combined stain methods. Beside the pathogenetic problems the Authors outline some histological methods useful for diagnostic purposes when a culture procedure for fungi is lacking.
