Isolated hypoglossal nerve palsy in a child.

Except for paresis of the facial nerve, mononeuropathies in childhood are very rare. Isolated hypoglossal nerve palsy is a rare condition and may be due to vaccination, aneurysms, trauma, dislocation of vertebrae, intracranial tumor or infectious processes such as infectious mononucleosis. In the literature, there are a few reports about isolated, unilateral hypoglossal nerve palsy1-9. In this report, we present a patient with isolated hypoglossal nerve palsy following urticarial lesions which might have been due to preceding viral infections.
