- Abstract: Spinal tuberculosis (TB) can be difficult to confirm microbiologically, and delayed treatment may result in irreversible neurological injury. We report the case of a 57-year-old Cambodian man who presented with a 2-month history of upper back pain and right-leg radiculopathy. Thoracic magnetic resonance imaging (MRI) demonstrated destructive spondylitis at T8–9 with epidural and paravertebral abscesses. Despite treatment with broad-spectrum antibiotics and decompression with biopsy at another hospital, serial MRI showed progression of the abscesses and worsening spinal cord compression, followed by bilateral lower-extremity weakness. Repeated acid-fast bacillus staining, mycobacterial culture, TB polymerase chain reaction, and histopathological examination all yielded negative results. A positive QuantiFERON-TB Gold result was considered supportive but not diagnostic evidence because interferon-γ release assays cannot distinguish latent from active TB. Nevertheless, the epidemiological background, MRI findings, chronic inflammatory pathology, and lack of response to non-specific antibiotics supported a clinicoradiological diagnosis of tuberculous spondylitis. Given the patient’s progressive neurological decline, marked destruction of T8 and T9, and overt instability, vertebral column resection was performed at T8–9, followed by anterior reconstruction with a titanium mesh cage and posterior fusion from T5 to T12. Empirical antituberculous chemotherapy was initiated on postoperative day 10. Motor strength improved, inflammatory marker levels decreased, and computed tomography and MRI obtained approximately 3 weeks postoperatively demonstrated stable reconstruction without a drainable fluid collection. This case illustrates that culture-negative spinal TB may require a clinicoradiological diagnosis, early empirical antituberculous therapy, and definitive anterior column reconstruction when progressive instability and neurological compromise are present.
