My father is suffering from severe pain in the lower back and entire leg (both legs). Family physician asked us to Get MRI Scan of LS Spineand of Right Hip Joint . MRI report of right HIP joint is Normal. MRI scan report of LS spine had the following conclusion: 1) Grade 1 anterolisthesis of L5 over S1 vertebral body with defect in the bilateral pars interarticularis and pseudobulging of the L5-S1 intervertebral disc , impinging the existing L5 nerve root and abutting the transversing S1 nerve roots bilaterally. 2) Changes of infective spondylo-diskitis involving the L4,L5 vertebral body and the intervening L4-L5 intervertebral disc with prevertebral and paravertebral soft tissue collection predominently on the right side along the illio-psoas muscles. This is most likely to represent changes due to Pott s spine.
