Bone tuberculosis: when consider this diagnosis?

The most common presentation of bone tuberculosis (TB) is called spondylodiscitis, or "Pott's disease", which is a difficult diagnosis due to its low prevalence in Switzerland. It should be considered in patients with persistent back pain, who are at high risk, such as migrant population and immunocompromised patients. Diagnosis is based on imaging and the detection of M. tuberculosis in biopsy of affected vertebra orparaspinal abscess, or even if active tuberculosis is proven in any other site. It's essential to initiate appropriate treatment as quickly as possible in order to avoid neurological complications and spinal deformity and to identify cases that will require a surgical therapy.
