A child with neurobrucellosis.

An 11-year-old boy presented with chronic meningitis followed by acute flaccid paralysis. The aetiology remained uncertain until the brucellar serology test became positive and there was a good response to specific antimicrobial therapy. Nerve conduction studies confirmed a proximal radiculopathy. Awareness of the condition and performance of the appropriate tests will differentiate neurobrucellosis from other chronic central nervous system infections.
