Aneurysm of the extracranial carotid artery is an uncommon lesion mostly found in the common carotid artery and its branches. Aneurysm of internal carotid artery is extremely rare.<BR>Generally symptoms are often suggested by the pulsatile nature of the lesion, in certain patients the enlarging aneurysm may cause a bulge in the area of the tonsillar fossa, hoarse voice and disphagia. Therefore the diagnosis is comparatively simple. But definitive diagnosis should be obtained by angiography that can discriminates other lesions.<BR>A case of an aneurysm of internal carotid artery obtained by computed tomography and angiography findings was reported. The patient was a 73 year-old female who complained of a left pharyngeal bulge. We abondoned the idea of doing an operation because of possible development of severe post operative symptoms of cerebral ischemia, and selected symptomatic treatment that avoids promoting aneurysm growth and rupture and keeping the present condition.<BR>Fortunately no change of symptom has been noted in seven months follow up.
