Background and Objectives: Brucellosis is a common zoonosis which still remains as a major health problem in certain parts of the world. Osteoarticular involvement is the most frequent complication of brucellosis, in which the diagnosis of brucellarspondylodiscitis is often difficult, since the clinical presentation may be obscured by many other conditions.

Case Report: We report an uncommon case of spondylodiscitis with paravertebral abscess. The diagnosis was established by using magnetic resonance imaging that was also confirmed by positive culture. This report describes a case of a 42-year-old woman. Serodiagnosis for brucella carried out at the onset of symptoms 4 months and 1.5 months before admission were negative. When the patient was admitted to our hospital, laboratory tests showed negative agglutination, and ELISA test for brucella and magnetic resonance imaging confirmed the presence of a paravertebral abscess around the affected disc and tissue edema. Culture of needle aspiration of abscess tissue was positive for brucella melitensis.
