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.

Brucellosis is a common global zoonotic disease, which is responsible for a range of clinical manifestations. Fever, sweating and musculoskeletal pains are observed in most patients. The most frequent complication of brucellosis is osteoarticular involvement, with 10% to 85% of patients affected. The sacroiliac (up to 80%) and spinal joints (up to 54%) are the most common affected sites. Spondylitis and spondylodiscitis are the most frequent complications of brucellar spinal involvement. Peripheral arthritis, osteomyelitis, discitis, bursitis and tenosynovitis are other osteoarticular manifestations, but with a lower prevalence. Spinal brucellosis has two forms: focal and diffuse. Epidural abscess is a rare complication of spinal brucellosis but can lead to permanent neurological deficits or even death if not treated promptly. Spondylodiscitis is the most severe form of osteoarticular involvement by brucellosis, and can have single- or multi-focal involvement. Early and appropriate diagnosis and treatment of the disease is important in order to have a successful management of the patients with osteoarticular brucellosis. Brucellosis should be considered as a differential diagnosis for sciatic and back pain, especially in endemic regions. Patients with septic arthritis living in endemic areas also need to be evaluated in terms of brucellosis. Physical examination, laboratory tests and imaging techniques are needed to diagnose the disease. Radiography, computed tomography, magnetic resonance imaging (MRI) and bone scintigraphy are imaging techniques for the diagnosis of osteoarticular brucellosis. MRI is helpful to differentiate between pyogenic spondylitis and brucellar spondylitis. Drug medications (antibiotics) and surgery are the only two options for the treatment and cure of osteoarticular brucellosis.
