Acquired and congenital internal carotid artery anomalies in two cases: an important threat for the otolaryngologist.

Diseases of the extracranial portion of the internal carotid artery (ICA) are rarely seen in the otolaryngology practice. We report two different pathologies of the ICA, which presented with otolaryngological symptoms. The first case was a 70-year-old woman with symptoms of chronic pharyngitis. On physical examination, a pulsatile mass at the right posterolateral oropharynx was identified. Magnetic resonance imaging revealed a tortuous ICA. No treatment was offered. The second case was a 75-year-old woman with a two-month history of upper neck mass. She did not have any additional complaints and her physical examination was normal except for the mass. Doppler ultrasonography showed a high fluid flow within the mass. Digital angiography demonstrated an ICA aneurysm. Because the patient refused any surgery, antiplatelet treatment was started.
