title: Isolated unilateral idiopathic transient hypoglossal nerve palsy.
abstract: A 52-year-old Caucasian man presented with sudden onset of difficulty in moving his tongue to the left with preceding left-sided headache with no neck pain. Earlier, he had self-limiting chest infection without rashes or tonsillar enlargement. His medical and surgical history was unremarkable with no recent trauma. Oral examination revealed difficulty in protruding his tongue to the left with muscle bulk loss and fasciculation on the same side, suggesting left hypoglossal nerve palsy. Examination of the rest of the cranial nerves and nervous system was normal. The patient's oropharyngeal and laryngeal examination was unremarkable with no cervical lymphadenopathy. He had normal laboratory investigations and cerebrospinal fluid examination. Extensive imaging of the head, neck and chest failed to reveal any pathology. Further review by an otorhinologist and rheumatologist ruled out any other underlying pathology. He made a good recovery without treatment. English literature search revealed very few cases of idiopathic, transient, unilateral hypoglossal nerve palsy.
