Diagnosis of tuberculous vertebral osteomyelitis (TVO) in a developed country and literature review.
METHODS
Review of medical and radiological records and literature to study the diagnosis of tuberculous vertebral osteomyelitis (TVO) and the differential diagnosis between TVO and pyogenic vertebral osteomyelitis (PVO).


OBJECTIVE
To identify the correct criteria for the diagnosis.


METHODS
National Spinal Injuries Centre, UK.


METHODS
(1) Medical and radiological records of 10 patients diagnosed as vertebral osteomyelitis and treated elsewhere but later admitted to the NSIC were reviewed retrospectively. (2) Medical literature on vertebral osteomyelitis were reviewed.


RESULTS
(1) Case review: Before the study, four of the 10 patients TVO had been diagnosed based on positive bacteriology. Of the other six, the diagnosis of PVO had been made in one based on positive blood culture of staphylococcus while in another without any positive result of bacteriology. The diagnosis had been uncertain in four because of negative results of both bacteriology and histology on both tuberculous and pyogenic infection. The author made the diagnosis of TVO in all 10 cases based on clinical manifestations and plain radiographs. Highly raised ESR with moderate rise of or normal WBC in eight cases supported TVO. Computer tomography and magnetic resonance imaging did not contribute to the differential diagnosis. Laminectomy in five patients led to some clinical improvement. The five patients without surgery deteriorated. Two of them died. (2) LITERATURE REVIEW: A total of 188 articles were reviewed. The crucial role of plain radiographs in the diagnosis of TVO and the high incidence of false-negative of tuberculosis in both bacteriological and histological tests were neglected in most articles. Polymerase chain reaction (PCR) was more reliable in diagnosing tuberculosis.


CONCLUSIONS
Clinical manifestations, discrepancy between ESR and WBC, plain radiographs and PCR are keys to a correct diagnosis of TVO.
