Abstract
Uni- or bilateral facial palsy is the most common neurologic manifestation of Lyme's disease and can occur as the first or only symptom. Early treatment avoids progression to the third stage of Lyme's disease. Two cases of Lyme's disease with facial palsy and lymphocytic meningitis in children aged 6 and 10 years, respectively, are reported. In both patients, ultrasonography of the neck demonstrated enlarged lymph nodes in the parotid glands and posterior neck, which were not felt on palpation. Ultrasonography of the parotid gland can help to make the diagnosis of Lyme's disease in children with acquired nontrauma-related facial palsy.
