A Rare Axonal Variant of Guillain-Barré Syndrome following Elective Spinal Surgery

Figure 2

Summary table of the patient’s motor and sensory findings on electrodiagnostic examination and EMG waveforms, respectively. The above examination shows no response of left peroneal motor nerve, left radial sensory nerve, left superior peroneal sensory nerve, left sural sensory nerve, right sural sensory nerve, and left ulnar sensory nerve. There is reduced amplitude of right peroneal motor nerve. Evaluation of left peroneal and right peroneal F-wave showed no response, and left tibial F-wave showed prolonged latency (not pictured above). Left and right tibial H-reflexes were abnormal. EMG needle evaluation of the right anterior tibialis showed no polyphasic potentials and reduced recruitment. Left anterior tibialis showed no polyphasic potentials. Left iliopsias showed no polyphasic potentials and reduced recruitment.
