Abstract:
The case is presented of a 62 year old man with a history of pulmonary tuberculosis, repeatedly consulting his primary care physician for treatment of analgesic / anti-inflammatory resistant back pain, and usually coincided with physical activity. It was initially diagnosed as mechanical pain, but in the absence of response to rest and treatment a magnetic resonance of the spine was requested, which reported bone metastases. The patient was then referred to Internal Medicine for further tests in hospital. The histopathology ruled out the presence of neoplastic cells, and imaging tests showed radiographic abnormalities in vertebral bodies (osteomyelitis-discitis) associated with epidural abscess, compatible with Pott's disease, a kind of tuberculous arthritis of the intervertebral joints.
