[Current aspects of spinal tuberculosis: apropos of 16 case reports].

We retrospectively studied the epidemiological, clinical, histological and evolutive aspects of vertebral tuberculosis diagnosed in all consecutive patients recruited in 2 Parisian hospitals between January 1990 and July 1997. The diagnosis relied on a vertebral involvement associated with evidence of tuberculosis (culture of local puncture yielded Mycobacterium tuberculosis) or presumption of tuberculosis (evidence of other tuberculous focus, histological data, good outcome under specific treatment). Sixteen patients (mean age: 41 years; sex ratio: 1.29) have been included; thirteen were migrants. The main symptoms, which appeared within a mean period of 3 months were vertebral pain (13/16) and alteration of patient's general conditions (8/16). RMN imaging showed spondylitis (10/16), spondylodiscitis (4/16) and involvement of posterior arch (8/16). Inflammatory syndrome was present in 14 cases. The diagnosis of vertebral tuberculosis was confirmed in 12 cases according to the results of culture and/or histological grounds of local puncture. The diagnosis of vertebral tuberculosis was presumed in the 4 other cases according to the isolation of M. tuberculosis from an other site (2 cases), the characteristic histological pattern of a lymphadenopathy (1 case), and a favorable outcome upon specific treatment (1 case). All the patients were cured without complications with the exception of one patient who developed a spinal cord compression.
