[Neurobrucellosis: clinical and therapeutic features]

Brucellosis is a common zoonosis endemic in many parts of the world. Neurologic involvement is a rare but serious complication and it occurs in 2 - 5% of cases. Neurologic signs can appear during the active phase of disease or later. Six cases of neurobrucellosis are described: meningoencephalitis in 2 cases, meningitis with brain abscess in 1 case, encephalomielitis in 3 cases. Diagnosis was made on the basis of history of the exposure to brucella, of serum and cerebrospinal fluid positive serology, of quantitative change in cerebrospinal fluid, on EEG, CT and MNR and favorable response to specific treatment (rifampin, rolitetracycline tirmethoprim-sulfamethoxazole). Neurobrucellosis should be suspected in case of neurological deficit in brucellosis endemic areas. Treatment of neurobrucellosis remains controversial: we recommend a regimen with rifampin 600 mg x 2 i.v. + tirmethoprim-sulfamethoxazole 2 ff x 2 i.v. for a period of 6-8 weeks.
