A Case of Diffuse Brucellar Spondylodiscitis.

Diffuse brucellar spondylodiscitis is the most severe subtype of osteoarticular brucellosis and is defined as a brucellar infection involving an entire vertebral body, typically a lumbar vertebra, with spread to the adjacent disc space, vertebra, and even extravertebral spaces, including epidural, paraspinal, or intramuscular locations. Although it is a relatively rare diagnosis in the US healthcare system, it should be considered in all patients with severe back pain, radicular symptoms, and a history of extensive exposure to an endemic area. Any delays in treatment can be associated with an increased risk of permanent neurological deficits or death. Here, we present a case of diffuse brucellar spondylodiscitis in a patient who presented to our facility with a history of extensive exposure to an endemic area. While an MRI can reveal pathognomonic findings in brucellar spondylodiscitis, for our case, it was nonspecific. The MRI provided early evidence of an infectious etiology which prompted immediate broad-spectrum antimicrobial coverage until causal organisms were identified and culture sensitivities directed targeted antibiotic therapy. The patient was able to recover over the course of four months without surgical intervention. At her final clinical follow-up, she had no neurological deficits and had complete resolution of her radicular symptoms.
