Skipped multilevel lesion as an atypical tuberculous spondylitis mimicking spinal metastasis: A case report

Abstract

Tuberculosis (TB) is one of major global health threats and leads to morbidity and mortality. TB is prevalent in low and middle income countries especially in Sub-Saharan Africa and South East Asia. M. tuberculosis usually affects the lungs. Spine is the most common extrapulmonary sites for TB after lymph nodes, accounts for 1% of all TB cases, and 50 to 60% of osteoarticular TB. In the case of spinal TB, two or more adjacent vertebrae are usually involved due to hematogenous spread of bacteria in which the vertebral arteries feed the two adjacent vertebrae. The incidence of multiplelevel non-contiguous spinal TB is 1.1 to 16% of all skeletal TB. Multiple-level non-contiguous, an atypical form of spinal TB is rare. It has insidious symptoms, often with diagnostic delays and a higher risk of permanent neurological deficits. We report a case of atypical TB spondylitis with non-contiguous multiple level of lesions mimicking multiple bone metastases.
