True aneurysms of the superficial temporal artery (STA) are quite uncommon. Only 14 such cases are described in the literature. Ultrasound scan (USS) is an appropriate and easily accessible non-invasive diagnostic modality, as it can show both the anatomical and flow characteristics of the aneurysmal vessel. Other conditions to be included in the differential diagnosis are haematoma, angiofibroma, eroding middle meningeal artery aneurysm, abscess or a parotid mass. Operative intervention is indicated to relieve symptoms as in this case, and to prevent rupture.
颞浅动脉真性动脉瘤相当罕见。文献中仅描述了14例此类病例。超声扫描（USS）是一种合适且易于获得的非侵入性诊断方法，因为它可以显示动脉瘤血管的解剖结构和血流特征。鉴别诊断中还应考虑的其他情况包括血肿、血管纤维瘤、侵蚀性脑膜中动脉瘤、脓肿或腮腺肿块。如本病例所示，需进行手术干预以缓解症状并预防破裂。
