She was assessed by neurology who requested brain and cervical MRI (Figure 1) and a study of cerebrospinal fluid, which were found to be normal.
Electromyography of the right peroneus longus (A) and left tibialis anterior (B) muscles show spontaneous pathological activity given by positive waves and fibrillations and left biceps (C) with increased recruitment with potentials of low amplitude and short duration. Nerve conduction velocity of the median motor nerve (D) was found to be normal, with decreased amplitude of potentials bilaterally, no sensory potentials are evoked. Neurophysiological study of 4 limbs with signs of fiber denervation and irritation with a myopathic pattern and polyneuropathic involvement with an axonal pattern.
