Pedicle involvement in tuberculous spondylitis and pyogenic spondylitis: Comparative magnetic resonance imaging study

AbstractAimMagnetic resonance imaging (MRI) comparison of the pedicle involvement in TB spondylitis and pyogenic spondylitis in relation to degree of spinal deformity, degree of vertebral body and disc damage and paravertebral and epidural abscess formation.Materials and methodsMRIs of 38 patients who had been diagnosed with and treated for spinal infection, 22 patients for TB spondylitis and 16 patients for pyogenic spondylitis were retrospectively evaluated for pedicle involvement, degree of spinal deformity, vertebral body and disc damage and paravertebral and epidural abscess formation.ResultsIncidence of pedicle involvement was highly significant more in TB spondylitis than in pyogenic spondylitis (P value
