Neurobrucellosis--a case report and review of literature.

Neurobrucellosis is a rare form of systemic brucellosis, a disease acquired through ingestion of unpasteurized dairy products, which may manifest as stroke, encephalitis, meningitis, or psychiatric disorders. Presently there is no known report ofneurobrucellosis in Nigeria, although consumption of unpasteurized dairy products is not uncommon in this country. In this report we present a 28 year old spinster with history of significant ingestion of unpasteurized cow milk and brucellosis of the brain diagnosed in our centre through brain magnetic resonance imagining (MRI) and brucella antigen agglutination test. Because of the indolent nature of brucellosis infection, it should be suspected in individuals with pyrexia of unknown origin so that early detection and treatment could prevent long-term sequelae such as focal neurologic deficits, hydrocephalus and psychiatric illness.
