title: Multiple sclerosis and positive Lyme serology.
abstract: As Lyme neuroborreliosis (LNB) may clinically mimic multiple sclerosis (MS) the presence of antibodies to Borrelia burgdorferi in serum of patients with a MS-like disease in non-endemic areas for Lyme disease may be troublesome. We report the case of a 45-year-old white female with the diagnosis of relapsing/remitting form of MS due to a 15-year history of optic neuritis and recurrent episodes of motor and sensation disturbance in the upper right limb and in both lower extremities associated with bladder dysfunction. A magnetic resonance imaging of the brain revealed multiple high intensity periventricular white matter lesions. The patient had been exposed to ticks but did not recall the presence of erythema migrans. ELISA for Lyme disease was positive in two different laboratories and the positive serology was confirmed by Western blotting. No convincing response followed treatment with ceftriaxone. Although it is clear that the patient had been infect by Borrelia burgdorferi the relationship of this spirochetal infection with the neurological disease could not be ascertained.
