A 54-year-old female presented with dyspnea on exertion and wheezing, with a negative response to inhaled beta-2 stimulating drugs and intravenous glucocorticoids. The major values of basal spirometric study were normal; however, the morphology of the flow-volume curve showed intrathoracic obstruction of large airways, with negative response to beta stimulating drugs. The bronchial provocative test with histamine was normal. Chest radiographs only showed a mild widening of the median mediastinum with left anterior tracheal displacement. Nuclear magnetic resonance showed a right aortic arch with tracheal strangulation.
一名54岁女性因劳力性呼吸困难和喘息就诊，吸入β-2激动剂药物和静脉注射糖皮质激素治疗无效。基础肺量计检查的主要指标正常；然而，流量-容积曲线的形态显示大气道存在胸内梗阻，对β激动剂药物反应阴性。组胺支气管激发试验正常。胸部X线片仅显示纵隔轻度增宽伴气管左前移位。核磁共振显示右位主动脉弓伴气管受压。
