Abstract

A case of 51-year-old male with the aneurysm of the superior thyroid artery was reported. Vascular diseases in the head and neck region are relatively rare and this case report was the second one since Biglioli reported first in 1977 as far as we referred . The patient visited our institution complaining of the mass on his left anterior neck and series of examination, including the dynamic CT and carotid angiography, revealed the aneurysm of the left superior thyroid artery. The aneurysm was surgically ligated and removed . One case of the superior thyroid aneurysm and eleven cases of the inferior thyroid aneurysm had been reported in the previous papers. Eight of thirteen cases containing this report presented sudden ruptures or dissections, two of which caused death. These previous reports pointed out that it was necessary to surgically remove this kind of aneurysm in the head and neck region as soon as possible after they were radiologically confirmed in order to avoid the possible disorder, for example sudden lethal airway obstruction due to thier ruptures or dissections.
