Vasculitic mononeuritis multiplex in patient with Lyme disease.

Lyme borreliosis is an infectious disease caused by the spirochete Borrelia burgdorferi. Neurological complications are frequently reported but the pathogenesis remains largely unknown. We report on a patient with positive borrelia antibodies at ELISA and immunoblotting and with histological and immunofluorescence study of peripheral nerve biopsy consistent with vasculitic neuropathy.
