Persistent idiopathic unilateral hypoglossal [corrected] nerve palsy: a case report.
Paralysis of the hypoglossal nerve, the twelfth (XII) cranial nerve, leads to atrophy, deviation of the tongue to the affected side, and varying degrees of fasciculation. The injury to the nerve can occur from its origin to the tongue itself. The causes of hypoglossal nerve palsy are well documented, but idiopathic, isolated nerve palsy that does not recover, is rare. To our knowledge we describe the first case that failed to resolve, and discuss the importance of meticulous investigation to make a diagnosis and rule out sinister disease.
