Extrapulmonary tuberculosis (TB) is uncommon but not rare. Bone and joint involvement constitute about 10% of extrapulmonary TB cases, with the spine being the most frequently affected site. Spinal TB patients typically present with back pain but other constitutional or pulmonary symptoms may be absent, rendering the diagnosis difficult. Standard radiographs only speak at a late stage of the disease, hence the interest of modern imaging, in particular computed tomography (CT) and magnetic resonance imaging (MRI), which allow for early diagnosis. We report three cases of paralytic hyperalgic lumbosciatic of tuberculosis origin. The diagnosis was based on the sectional imaging associated with biological elements of high presumption and a favorable evolution under anti-tuberculosis treatment.
