TB spondylitis is believed to involve multiple spianl segment than pyogetic spondylitis. The earliest and most common radiographic finding is narrowing of the disc space in pyogenic spondylitis. It is due to the disc destruction by proteolytic enzyme.as to tuberous spondylitis, the disc space is preserved more than pyogenic spondylitis from the lack of proteolytic enzyme. pyogetic spondylitis create a mild~moderate bony destruction than tb, thus the certebral body enhancement is homogeneous than tb. paraspinal abscess is frequently found in pyogenic spondylitis; but well-defined paraspinal abnormal signal, thin and smooth abscess wall and presence of paraspinal or intraspinal abscess are more suggestive of tuberculous spondylitis than of pyogenic spondylitis Company name Company slogan here Company name Company slogan here .
