Abstract:
OBJECTIVE: The purpose of this study is to analyze the patterns of intervertebral disc enhancement seen in infectious spondylitis, differentiate between two groups(tuberculous vs pyogenic spondylitis). METHODS: Between January 1994 and December 2002, 83patients underwent operative procedure with confirmed to histopathologic evaluation. Magnetic resonance(MR) images were obtained in all patients and were analyzed retrospectively. 57patients had tuberculosis and 26patients were infected by pyogens. The patterns of gadolinium enhancement of disc were classified into 4 types(post's classification): Type I, non-enhancing; Type II, enhancement of the peripheral rim; Type III, Type II with central area and partial endplate; Type IV, general enhancement. RESULTS: The enhancement patterns observed were as follows: Common pattern of tuberculous spondylitis was Type II, and pyogenic spondylitis was Type III.(p<0.01) This difference may result from pathophysiologic varieties of organisms. CONCLUSION: Careful preoperative MR analysis of the patterns of disc enhancement occuring in infectious spondylitis can be useful for differentiating between the tuberculous and pyogenic spondylitis.
