We describe a patient in whom a previously asymptomatic elongated styloid process eroded simultaneously through the internal carotid artery (ICA) and oropharynx, causing hematoma and hemoptysis. The presence of an identical twin prompted thorough genetic evaluation.
Elongation of the styloid process is an anatomic variant that, when associated with symptoms such as pain and dysphagia, is termed Eagle syndrome.1 We present a case of a previously asymptomatic aberrant styloid that presented suddenly with disruption of the ICA.
