Muscle biopsy revealed a non-inflammatory necrotising myopathy. B. burgdorferi infection was confirmed by a considerable rise of specific IgG antibodies. A course of high dose steroids alleviated the myalgias, but paresis began to improve only after treatment with antibiotics. Our observations confirm that B burgdorferi can cause, through an undertermined mechanism, a necrotising myopathy, in addition to the wide spectrum of already known neurological complications. ER -
