A 41-year-old man presented with lower extremity weakness and numbness that began 48 h prior to presentation. He noted progressive difficulty in ambulation, numbness and tingling from the lower abdomen to the toes, and difficulty initiating urination. He had been diagnosed with pulmonary and spinal tuberculosis 8 weeks previously after presenting with upper back pain after a mechanical fall and was undergoing anti-tuberculosis medical therapy. At the time of initial diagnosis he had pulmonary and T6-T7 bone involvement, but no epidural involvement. He was compliant with drug therapy and had documented negative sputum tests after 2 weeks of treatment.
The most common cause of delay in the diagnosis of bony tuberculosis is failure to consider the diagnosis, especially in patients who have normal chest radiographs. More than 50% of such patients do not have evidence of active chest disease . Among patients that manifest bony tuberculosis, the spine is involved in 50% of patients. Of those involving the spine, the thoracic spine is the site of infection in 50%, the cervical spine in 25%, and the lumbar spine in 25% [2, 3]. Like tubercular infection of the spine, epidural abscess is commonly misdiagnosed as a benign cause of back pain. Most epidural abscesses are not diagnosed until the patient has neurologic deficits or a fever . In any mass effect on the spine, neurosurgical consultation should be obtained, emergently. Empiric therapy for active TB infections is multi-drug therapy. Treatment is continued for at least 6 months.
