EMR report. he did have one lower extreminty motor nerve conduction that was in the 20's consistent with a demyelinating neuropathy, but the distal latency was not prolonged- more suggestive of an axonal neuropathy-and the motor conductions elsewhere were higher, also suggestive of an axonal prosecc. also he unusually had a preserved sural sensory resonse.So whereas one piece of evidence hints to a demyelonating process more of the evidence favors an axonal process and there is a patchiness to it that would go with mononeuropathy multiplex such as one could see with vasculitis and infiltrative processes.Nerve conductions showed evidence of a severe axonal neuropathy, but the distal latencies of both peroneal nerves also suggested an additional demyelinating componet.EMg needle exam was consistent with a neuropathic process. In veiw of asymmetery of the findings a superimposed L-5, S-1 radiculopathy or a sciatic mononeuropathy could not be excluded.
Impression: This is an abnormal study.
There is evidence of severe, chronic and ongoing, mixed sensorimotor polyneuropathy.There is a relative degree of asymmetry with the right side being more affected.In the setting of severe polyneurophy a superimposed L5-S1 radiculopathy or a mononeuropathy /ie,sciatic neuropathy cannot be excluded.
