instruction: hi doctor this query is regarding my dad he has been limping for a year now he is a construction worker and about two years ago he accidentally fell down from the first floor he reassures me that his left leg limping is not due to the fall he had about 20 sessions of physical therapy he went to a pain specialist who injected him with steroid injections but that did not help the pain specialist also performed an electro test to see the response reaction in both feet the right one jumped and the left one did not he said he barely felt any sensation in his left leg his left leg is not responsive and he cannot carry it around we had an mri and consulted a neurosurgeon the neurosurgeon said that he is not to be operated on the result of his mri is as follows 47 years old with radiculopathy correlation is made with prior mri of the thoracic spine findings are mild spondylotic changes are seen within the cervical spine with disc desiccation multiple levels ca c3 there is a shallow central disc herniation impression on the thecar sac c3 ca no focal disc herniation or neurocompressive changes are seen ca c5 shallow central disc herniation impresses on the thecar sac c5 ca there is central disc herniation with effacement of the ventral csi ca shallow central disc herniation impresses on the thecar sac ca to no focal disc herniation or neurocompressive changes are seen vertebrae the vertebral bodies demonstrate normal height and marrow signal characteristics spinal cord there are multiple foi of abnormal to signal within the substance of the spinal cord one at the ca level and one at ca it is unclear whether this reflects myelomalacia versus the possibility of a demyelinating process clinical correlation as well as evaluation of the intracranial compartment with mri of the brain is recommended craniovertebral junction the craniovertebral junction is unremarkable mild prominence of the nasopharyngeal soft tissues is incidentally noted please correlate with direct clinical examination impression is multiple foi of abnormal to signal within the substance of the spinal cord as described these may be on the basis of myelomalacia however given the patient age the possibility of a demyelinating process is not excluded clinical correlation as well as evaluation of the brain with mri scanning is recommended mild spondylotic changes within the cervical spine with shallow central disc herniation at ca c3 ca c5 and ca levels slightly larger central disc herniation c5 ca with effacement of the ventral csi mild prominence of the nasopharyngeal soft tissue as I want an unbiased opinion please consider only the results and not the possible diagnosis my questions are what are the possible causes of these what are the outcomes in the future can anything be done to regenerate neural tissue and myelin finally how many herniated discs does he actually have
output: hello for further information consult a neurologist online
