A Rare Form of Bursitis with Negative Serology: A Case Report and Literature Review.

Brucellosis is still endemic in certain parts of the world including the Mediterranean, the Middle East, Latin America, and African regions. Osteoarticular manifestations are common presenting features. Brucellosis presenting as prepatellar bursitis has already been reported. We present a case of seronegative olecranon bursitis with positive blood and aspirate cultures. The patient improved remarkably by treatment with streptomycin and doxycycline with no evidence or relapse.
