Horner syndrome due to vertebral artery stenosis.
The author reports a rare case of Horner syndrome in a patient who resulted from stenosis of the vertebral artery after blunt trauma. A 31-year-old man was transferred to our department for evaluation of left medial orbital wall and nasal bone fractures. Five days ago, he was hospitalized due to multiple second to fourth rib fractures of the right chest following blunt trauma of the face, neck, and chest. Surgery was performed. Ten days later, he complained of drooping of the right eyelid. Physical examination revealed a discrete miosis and ptosis with normal levator function in the right eye. A workup for Horner syndrome was performed. Magnetic resonance angiography of the head and neck revealed a stenosis of the distal part of the right vertebral artery without the abnormality of carotid artery. He wore a cervical collar and underwent anticoagulation. However, Horner syndrome was not resolved over the next 12 months. Acute traumatic Horner syndrome may be associated with vertebral artery dissection in which the possibility of life-threatening injury can be masked.
