Abstract

We report an 84-year-old woman with left lower limb muscle weakness and numbness who also had weakness in her right lower limb, which showed spontaneous partial improvement. Neurological examination revealed lower extremity weakness and sensory disturbance in all modalities, predominantly distally on the left side. Laboratory studies yielded normal results, except for a slightly high erythrocyte sedimentation rate. Nerve conduction studies showed axonal neuropathy in the right tibial nerve, and loss of action potentials in other lower limb nerves. Histological study of the left sural nerve revealed mainly loss of axons and differences in the density of fascicules in the axons. In addition, inflammatory cells infiltrated around small blood vessels. Therefore, we diagnosed nonsystemic vasculitic neuropathy.<br> Magnetic resonance imaging revealed that she also had spondylosis deformans and radiculopathy, which was more difficult to differentiate. Neural biopsy was important for diagnosis.<br>
