      Hi,
      I am new to the forum and was wondering if anyone had EMG/NCS showing acquired demyelinating disorders but all CSF data within normal range.

      EMG/NCS report:
      Nerve conduction studies of the left upper and lower extremities showed reduced fibular and tibial amplitudes with 45% conduction block in the fibular nerve distal to the fibular head and 67% conduction block in the tibial nerve. Temporal dispersion was also noted in both waveforms at proximal stimulation sites. The tibial F-wave response was poorly formed and of prolonged latency when compared to F-estimate. Medial plantar sensory nerve action potential was absent. Needle EMG showed borderline increased size of voluntary motor units in tibialis anterior.

      CLINICAL INTERPRETATION: There is electrodiagnostic evidence of a sensorimotor demyelinating
      peripheral neuropathy. The presence of temporal dispersion and conduction block is more typically seen in acquired demyelinating disorders.

      Did blood work and spinal tap and they are all in normal range. Still waiting to hear back from neurologist. Posting here to see if anyone had similar findings and what was the diagnosis.

      Thanks a lot in advance.
