AB1454 CLINICAL AND BIOLOGICAL FACTORS CORRELATED WITH MAGNETIC RESONANCE IMAGING RESULTS IN TUBERCULOUS SPONDYLODISCITIS

Background Tuberculosis is still endemic in Tunisia. Although pulmonary localization the most common, other localizations, including osteo-articular involvement, are increasingly diagnosed. Tuberculous spondylodiscitis (SPDT) or Pott’s disease an infectious involvement of disc-vertebrate couple, caused by tubercular bacillus (Mycobacterium tuberculosis). Magnetic resonance imaging (MRI) sensitive (95-100%) and early abnormal exam. Objectives Our aim was to study correlation contributing factors, epidemiological, clinical, biological, radiological therapeutic data with positive signs spinal MRI. Methods We conduct a retrospective descriptive single rheumatology department. Data were collected from observations patients hospitalized past 20 years (2000-2020) who have been diagnosed SPDT. Epidemiological, radiological, analyzed. Each patient had Positive individualized, represented intervertebral disc vertebral body visualization paravertebral abscess. Results Fifty-two cases SPDT (37F/15M). The mean age population 55.21±17.79 [19-91]. Thirty-three (69.2%) classified as young versus 16 elderly (30.8%), female predominance both groups (69.4% 75% respectively, p = 0.57). diagnosis tuberculous facilitated sought our which by: achievement diffuse T2 hypersignal (56.5%) circumferential increase signal sp T1 Gadolinium (50.9%), Involvement moderate extensive condensation (60.4%), macrogeodes (60.4%) heterogeneous spT1 Gado (52.8%) abscess (51.9%). Correlations made between favouring MRI, objecting that six parameters statistically significant MRI strongly suggestive SPDT: Hospitalization duration correlated disk (p= 0.02; r= - 0.38), Hemoglobin rate 0.03; 0.34), initial lymphocytes 0.04; 0.47). extra-vertebral tuberculosis location -0.96), extent (p < 0.001) 0.001). neurological clinical -0.33) surgical treatment Conclusion frequent condition needs be treated rapidly. Spinal first-line exam case suspicion. Clinical, biological images highly diagnosis. Disclosure Interests None declared
