SAT0500 A Comparative Analysis of Radiological Findings between Tuberculous and Brucellar Spondylodiscitis

Background Tuberculous and brucella spondylodiscitis are endemic in tunisia. Both present in various pathological patterns, but there are significant radiological differences that permit a presumptive aetiological diagnosis and orient the initial empirical treatment. Objectives The aim of this study was to compare radiological features between these two diseases. Methods A retrospective monocentric study was performed. Patients diagnosed with tuberculous spondylodiscitis (TSD) or brucellar spondylodiscitis (BSD) between 2008 and 2016 were included. Clinical status and radiological results were assessed. Results A total of 33 patients were enrolled in the study including 17 men and 16 women. The mean age was 59 years (29–96 years). Twenty four had TSD (72,8%) and 9 BSD (27,2%). CT scan was performed in 9 cases and magnetic resonance imaging (MRI) in 24 cases. For both TSD ans BSD the most common region affected wad lumbar spine (respectively 58% and 77%). Preverebral, paravertebral, epidural and psoas abscess formations were significantly more frequent in TSD compared with BSD [p=0,01]. When considering neurological complications such as epiduritis and cord compression, TSD was not significantly different from BSD [p=0,17]. Conclusions The results of this study show that TSD is a more suppurative disease with abscess formation. Disclosure of Interest None declared
