Abstract
Brucellosis is a zoonotic disease that is endemic in Saudi Arabia. It is transmitted to humans through direct contact with infected animals or by consuming unpasteurized dairy products. A 36-year-old Saudi man presented with left hip pain, fever, and a history of consuming unpasteurized milk. Sacroiliitis was documented by positive results from serological tests (ELISA) and magnetic resonance imaging. Treatment consisted of non-steroidal anti-inflammatory drugs (NSAIDs), doxycycline, rifampicin, and IV gentamicin.
