Tonsillectomy is one of the most common surgeries performed in the United States.1 A rare vascular complication of tonsillectomy is extracranial internal carotid artery (ICA) pseudoaneurysm, which occurs when a tear in the arterial wall leads to a hematoma and subsequent development of a periarterial fibrous capsule. Expeditious treatment is required to avoid life-threatening complications.
