Traumatic multiple lower cranial nerve palsy: a case report and review of the literature.

Lower cranial nerve palsy, also known as Collet-Sicard syndrome, is a fairly rare pathology characterized by unilateral palsy of the IX-X-XI-XII cranial nerves. We report a multiple cranial nerve palsy developing after a head trauma that might have been considered negligible. A 16-year-old boy was admitted with swallowing and articulation problems and difficulty lifting one shoulder after a head trauma suffered during a football match. No pathology was revealed in the subsequent imaging. Cranial nerve palsies due to head trauma are very rare. Awareness of the possibility of such a condition, leading to early recognition and treatment, may result in significant functional recovery.
