We report the case of a 29-year-old patient without medical history presenting with dysphonia associated with left unilateral vocal cord paralysis. The patient underwent a contrast-enhanced computed tomography with an angiographic arterial phase of the head, neck and chest, and the only significant finding was the presence of a large, aberrant right bronchial artery originating directly from the aortic arch, where the recurrent left laryngeal nerve loops. After excluding alternative etiologies, the hypothesis of neurovascular conflict between this vessel and the recurrent left laryngeal nerve was formulated. To the best of our knowledge, this is the first case reported in the literature. Thanks to its high spatial resolution, contrast-enhanced computed tomography is the examination of choice for the study of anatomical variants and should be included in the routine work-up of patients presenting with unilateral vocal cord paralysis.
我们报告了一例29岁无病史的患者，其表现为与左侧单侧声带麻痹相关的发音困难。该患者接受了头部、颈部和胸部的动脉期增强计算机断层扫描血管造影，唯一显著的发现是存在一条直接起源于主动脉弓的粗大异常右支气管动脉，而左喉返神经在该处环绕。在排除其他病因后，提出了该血管与左喉返神经之间存在神经血管冲突的假说。据我们所知，这是文献中报道的首例病例。由于其高空间分辨率，增强计算机断层扫描是研究解剖变异的首选检查方法，应纳入单侧声带麻痹患者的常规检查流程。
