Spinal brucellosis

Abstract

The findings in 44 patients with back pain and brucellosis are described. Radiological changes tended to occur in older patients with a longer duration of disease. The younger patients more often experienced an acute arthritis with sacroiliitis resembling a reactive disease. Bone scanning was more sensitive than radiographs, particularly in detecting acute sacroiliitis and hip involvement. The lumbar spine was the most frequently involved site although no part of the spine was spared. Extensive destruction of a vertebral body with little involvement of the adjacent vertebrae, lower lumbar spondylolysis and spondylolisthesis, and discitis with calcification were striking radiological findings hitherto undescribed in brucellosis. Computerized axial tomography (CAT) scanning revealed vertebral-arch destruction in three cases of spondylolisthesis. Circumferential sclerosis of the vertebral bodies was another CAT-scan finding.
