###Human: Kindly explain well defined altered cystic signal intensity along nerves in MRI. ###Assistant: Hello. Regarding your question, I would explain that this cyst is not related to her clinical situation. These cysts are since birth and are usually asymptomatic. In my opinion her symptoms could be related to the bulging disc in L5S1 level, which may need surgery. For this reason I would recommend consulting with a spinal surgeon. Another treatment option would be steroid intrathekal injection. You should discuss with her doctor on the above treatment option.
