Of 392 patients suspected of having neuro-Lyme disease, 66 patients proved to have the disease on the basis of clinical criteria, serologic results, and response to treatment. Seven of these 66 patients showed foci of T2 prolongation in the cerebral white matter, one had an enhancing lesion with edema, and three demonstrated nerve-root or meningeal enhancement. Of the seven patients with foci of T2 prolongation in the white matter, three were an age at which white matter findings due to small-vessel disease are common. In cases of nerve-root or meningeal enhancement, Lyme disease should be considered in the differential diagnosis in the proper clinical setting. |
