Brucellar spondylodiscitis with rapidly progressive spinal epidural abscess showing cauda equina syndrome.

Early diagnosis of Brucellosis is often difficult in the patient with only single non-specific symptom because of its rarity. We report a patient with Brucellar spondylodiscitis, in which the low back pain was the only symptom and the magnetic resonance imaging (MRI) showed not radiographic features about infection at initial stage. He was misdiagnosed as a lumbar disc herniation for inappropriate treatment in a long time. The delay in diagnosis and correct treatment led to rapid progression of the disease and severe complications. The patient was treated successfully with triple-antibiotic and surgical intervention in the end. Brucellar spondylodiscitis should always be suspended in the differential diagnosis specially when the patient comes from an endemic area or has consumed dairy products from animals in such an area and comprehensive examination should be done for the patent to rule out some important diseases like Brucellosis with sufficient reasons.
