Pott's paraplegia and role of neuroimaging in resource limited setting: A case report and brief review of the literatures.

BACKGROUND: Tuberculosis (TB) is the leading cause of morbidity and mortality in low and middle income countries (LMIC). Approximately 50% of cases of skeletal TB involve the spine. Failure to identify and treat these areas of involvement at an early stage may lead to serious complications such as vertebral collapse, spinal compression, and spinal deformity. The clinical and radiologic features of Pott's disease may mimic other spine diseases such as, metastatic lesions and other infectious etiologies, this is especially imperative in older patients.

CASE REPORT: We report a 60-year-old right handed male patient presented with back pain, paraparesis, and sensory symptoms 2 weeks duration. He has history of dry cough, fatigue, and reduced appetite, but no history of weight loss, fever, night sweat, and bowel/bladder incontinence. No contact history with TB patients. He has a borderline hypertension and diabetes mellitus. Serology for HIV was negative. Thoraco-lumbar magnetic resonance image (MRI) showed destruction of L2 and L3 vertebral body and the inter-vertebral disc; with T2 hyper and T1 hypointensity of the affected vertebral bodies. Probable tuberculous spondylitis with paraparesis was considered and the patient was initiated on antituberculous regimen and short course steroid therapy. After five months treatment, the patient showed significant clinical and radiological improvement.

CONCLUSION: In summary, the present case describes, a patient with Pott's paraplegia due to probable spine tuberculosis and showed significant clinical and radiological improvement following initiation of antituberculous drugs and short course of steroid; indicating the crucial role of imaging in the diagnosis of TB, especially in resource limited settings.
