<s>[INST] Hi! I just had an MRI and I haven t seen a doctor to explain to me the impression. Please explain what it means. Please see below. Thank you. Grade 1 spondylolisthesis , L5 over S1 vertebrae Right paracentral disc with posterolateral annular fissure , L4-L5 level with indentation of the ventral thecal sac , narrowing of the right neuroforamina and abutment of the right descending L5 nerve root . Filum terminale lipoma. [/INST] Hi, Thank you for posting your query. Your MRI report suggests mild degenerative changes in the lumbar spine region.  There are mild disc bulges, which are compressing the lumbar nerves. There is also a mild listless- forward movement of the lowest lumbar bone. These changes could result in back pain and pain along the legs. Initial treatment would be with medications such a pregabalin and physiotherapy. Best wishes, Chat Doctor.  </s>
