Isolated hypoglossal nerve palsy in a child.

We report an 11-year-old boy who had isolated hypoglossal nerve palsy one week after symptoms and signs of urticarial lesions. Neuroradiological examinations and other investigations for etiology of hypoglossal nerve palsy and urticaria were normal. We suggest that all patients with hypoglossal palsy must be carefully evaluated for atypical findings and etiologies.
