A young @entity1 with a clinical history characterized by recurrent @entity1729 , occurring since early infancy, was referred to our hospital. When the @entity1 was a young @entity1 , she underwent sweat @entity2865 test, serum analysis of immunoglobulins, and evaluation of blood lymphocyte subsets; all these diagnostic tests were normal, as well as chest X ray aside from @entity55 episodes. Skin prick tests were positive for several different allergens, and a diagnosis of @entity2023 was made. At the age of 11 years, she started to complain of @entity354 ( @entity354 ) symptoms, and a gastroscopy detected a @entity357 with @entity2910 . Despite pharmacologic treatments for @entity2023 and @entity354 , the @entity1 continued to complain of chronic cough, associated with @entity1224 and recurrent @entity1729 treated with antibiotic therapy. For the first time in her life, we performed a spirometry that showed a flow-volume curve characterized by a plateau in the expiratory phase, suggestive of an central @entity1224 . Bronchoscopy demonstrated a compression of the distal portion of @entity825 . Computed tomography (CT) angiogram revealed a double aortic arch. Barium enhancement evidenced an esophageal compression. A surgical division of the smaller of the two arches was then performed. Therefore, we strongly suggest to perform lung function tests in all cases of unexplained respiratory complaints.
