Superior vena cava (SVC) aneurysms are a rare entity. The majority of the literature is in the form of case reports. SVC aneurysms are often an incidental finding with iatrogenic, congenital, or idiopathic etiologies. Treatment goals focus on preventing theoretical rupture or thrombus formation. Management options include observation, conservative medical management, surgical excision, and thrombin injection. We present a 73-year-old female with an incidental SVC aneurysm discovered on computed tomography (CT) of the thorax. The patient was observed without intervention for greater than 6 years. No complications were attributable to the SVC aneurysm during follow-up or over the course of the patient's life.
上腔静脉（SVC）动脉瘤是一种罕见的病症。大多数文献都是病例报告的形式。SVC动脉瘤常常是在因医源性、先天性或特发性病因进行检查时偶然发现的。治疗目标主要是预防理论上的破裂或血栓形成。治疗选择包括观察、保守药物治疗、手术切除和凝血酶注射。我们报告一例73岁女性患者，其在胸部计算机断层扫描（CT）时偶然发现SVC动脉瘤。该患者未接受干预观察了6年多。在随访期间或患者的整个病程中，未出现任何归因于SVC动脉瘤的并发症。
