The oldest patient in literature of spontaneous true giant superficial temporal artery aneurysm

BACKGROUND: Superficial temporal artery (STA) aneurysms are very rare compared to vascular aneurysms of other regions. They are divided into two as true and pseudo. Pseudoaneurysm were much more common and often depend on an etiological factor but spontaneous true aneurysms are extremely uncommon and the etiologic causes are not clear yet. CASE PRESENTATION: We present a 91-year-old female patient who consulted to us with swelling in front of the ear; there was no history of previous surgery or any trauma. The patient had a pulsatile mass in the preauricular region, which started 4 years ago and growed faster for the last 2 months. CONCLUSION: There was a mass consistent with a saccular type aneurysm whose continuity was observed with the temporal artery in imaging studies. The mass was excised under general anesthesia. The patient whose pathological examination was a true STA aneurysm was discussed in the light of the literature.
