hi i have had problems  with spasticity in my lower limbs easpecially from my knees downwards i finally had a consultation with neurologist two days ago and i didnt really understand what he has put me back in for MRI scan of my brain and cevical spine as i have already had CAT scan and MRI thoracumbular that were essentially unremarkable he remarked that there was a severe level of spsticiity in lower limbs  he suspect i may have cervical  cord lesion and bran stem lesion  what this can u explain and what the significance of said lesions if proved accurate
Hi, Thank you for posting your query. Spasticity in lower limbs (legs) can occur due to a disease in corticospinal tracts, which extends from brain to the spinal cord. In your case, MRI of the thoracolumbar spine has been done, and it is normal. However, we still need to examine the brain and cervical spine for any disease, as that too could cause spasticity of legs. Hence, your doctor has ordered for MRI of brain and cervical spine. CAT scan is not as sensitive and specific in finding out minor brain diseases or small lesions, hence it can not be relied upon 100%.  I hope it helps. Please get back if you have any more queries. Best wishes, Chat Doctor.
