Two patients with neck masses were evaluated, one with computed tomography (CT) and the other with magnetic resonance (MR) imaging. Each mass was correctly identified within the carotid sheath. The correct diagnosis-thrombosed cervical carotid aneurysm--was not considered, necessitating unexpected repair of the aneurysm or artery. Although rare, aneurysm of the cervical carotid artery should be considered in the differential diagnosis of a carotid sheath mass between the jugular vein and carotid artery. Peripheral calcification or enhancement on CT scans and a peripheral signal void on MR images are especially suggestive of the diagnosis.
对两名有颈部肿块的患者进行了评估，一名接受了计算机断层扫描（CT），另一名接受了磁共振（MR）成像。每个肿块都在颈动脉鞘内被正确识别。但未考虑到正确的诊断——颈段颈动脉血栓形成性动脉瘤，从而导致了对动脉瘤或动脉进行意外修复。尽管罕见，但在鉴别诊断颈静脉和颈动脉之间的颈动脉鞘肿块时，应考虑颈段颈动脉动脉瘤。CT扫描上的外周钙化或强化以及MR图像上的外周信号缺失尤其提示该诊断。
