Vertebral Osteomyelitis in Qatar

SUMMARY Twenty‐eight cases of vertebral osteomyelitis were diagnosed at Hamad General Hospital in Qatar between January 1988 and December 1991:16 (57.2%) cases were tuberculous spondylitis, 6 (21.4%) Brucella spondylitis, 3 (10.7%) Staphylococcus aureus spondylitis, 2 (7.1%) Salmonella spondylitis, and 1 (3.6%) Pseudomonas cepacia spondylitis. Plain vertebral x‐ray films and CT scans were abnormal in all patients. Bone and gallium scans were abnormal in 87.5% and 64% of cases respectively. Clinical manifestations, haematological and radiological investigations were not able to differentiate between the causes. Serological tests were helpful in diagnosing Brucella spondylitis. CT‐guided needle biopsy was able to identify the aetiology in 90% of cases. We conclude that invasive tests are still needed to establish the microbiological diagnosis and to guide antimicrobial therapy in most cases of vertebral osteomyelitis.
