Cerebral torulosis: clinical features and correlation with computed tomography.

Cryptococcus neoformans (Torula histolytica) is an uncommon cause of infection in the central nervous system. We review 15 cases from all over Queensland which have presented in the last 6 years. Computed tomography (CT) studies were abnormal in 73.5%, with mass lesions and hydrocephalus being the commonest findings. Notable findings were: the disproportionate severity of clinical signs and symptoms as compared with the CT findings, which often were either normal or demonstrated only small granulomas without significant mass effect, absence of enhancement in granulomas in two cases and observation of calcification during treatment in one patient.
