Inclusion Criteria

Both genders; age: 1 day of life up to 100 years; diagnosis of tuberculosis of the spine. Diagnosis will be defined by: isolation of the etiological agent or by clinical and radiographic criteria characteristic of tuberculosis vertebral involvement and or pathological examination compatible with tuberculosis and / or positive therapeutic test. Isolation of the agent will be considered the presence of BAAR by the Ziehl-Neelsen method, molecular rapid test (real-time PCR) and culture for mycobacteria. The radiographic findings are visualized in radiographs of the spine according to the affected level, in the posteroanterior and profile incidences, with the following findings: aneurysmal abscess, sacral lesions, disc space reduction, vertebral collapse, kyphosis, calcification. The findings found on computed tomography are a decrease in the height of the vertebral body, osteolysis in the terminal plates of the vertebral bodies adjacent to the disc, pre-vertebral abscess, paravertebral abscess. Magnetic resonance imaging findings are hyposignal of the affected disc in weighted images at t1; hypersignal of the disc and the vertebral plateaus adjacent to the disc in t2-weighted images; epidural involvement; paraespinal abscess with a smooth abscess wall. Clinical Criteria: Indolent chronic infection associated with leukocytosis and changes in inflammatory tests, CRP and HSV, associated or not with the positive tuberculin test; Anatomopathological examination: The presence of epithelioid macrophage proliferation constituting confluent granulomas with presence of giant Langerhans cells with central foci of caseous necrosis and surrounding lymphocytic infiltrate was considered a characteristic of TB, with positive BAAR using the Ziehl-Neelsen method . The samples were submitted to routine methods for optical microscopy: 10% formaldehyde fixation, paraffin blocks cut into a 3 micron thick microtome and stained by hematoxylin-eosin (HE), Grocott (for fungi research) and Ziehl-Neelsen (for the BAAR survey). The biopsies were processed according to routine of the laboratory of Pathological Anatomy;
