Abstract

FAGUNDES-PEREYRA, Walter J. et al. Central nervous system paracoccidioidomycosis: analysis os 13 cases. Arq. Neuro-Psiquiatr. [online]. 2006, vol.64, n.2a, pp.269-276. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2006000200018.

Paracoccidioidomycosis (PCM) is a systemic granulomatous disease caused by Paracoccidioides brasiliensis, prevalent in Latin America, particularly in Brazil. Central nervous system (CNS) involvement occur in about 10% of cases. Thirteen patients with PCM involving CNS were studied considering clinical manifestation, neuroradiology and treatment modalities. Age ranged from 30 to 71 years-old (M= 47.1 ± 11.6 Me= 46). There were eleven men and two women. The most frequent symptoms were motor deficits (53.8%), cognitive disturbance (53.8%), weight loss (46.1%), headaches (46.1%) and seizures (46.1%). The diagnosis was confirmed by the demonstration of P. brasiliensis. Granulomatous forms were present in all patients. Four (30.8%) of them had also meningeal involvement (mixed form). Computerized tomography (CT) scans were obtained in all cases and magnetic resonance imaging (MRI) was used in one case. Serology for HIV was done in ten patients (76.9%), and all the tests were negatives. Amphotericin B was used in twelve patients (92.3%), one of them by intraventricular infusion. In eight patients (61.5%), trimethopim and sulfamethoxazole were used, and, in two (15.4%), sulfadiazine and pirimetamine. Fluconazole, ketoconazole and itraconazole were each one used in a different patient as well. Six patients died (46.1%) and seven (53.9%) had satisfatory outcome. The follow-up period ranged from 2 to 74 (M=30.9) months. In conclusion, the CNS involvement in paracoccidioidomycosis is more frequent and more serious than thought before. The clinical manifestations, CT scans and MRI findings are not specific of paracoccidioidomycosis.
