# Right-Sided Aortic Arch Presenting as Chronic Cough in a 50-Year-Old Patient With DiGeorge Syndrome: A Report of a Rare Case

## TL;DR

A rare case of a right-sided aortic arch causing chronic cough in a 50-year-old man with DiGeorge syndrome is reported.

## Contribution

Highlights a rare anatomical cause of chronic cough in DiGeorge syndrome and emphasizes multidisciplinary collaboration.

## Key findings

- Right-sided aortic arch was identified as the cause of chronic cough in a DiGeorge syndrome patient.
- CT imaging and bronchoscopy confirmed progressive tracheal compression over several years.
- The case underscores the need for considering vascular anomalies in unexplained chronic cough.

## Abstract

A right-sided aortic arch is a rare congenital vascular anomaly that can be seen in individuals with 22q11.2 microdeletion syndromes, such as DiGeorge syndrome. Although most patients are asymptomatic, airway or esophageal compression may occur in a small subset of individuals. In this case, a 50-year-old male patient with DiGeorge syndrome presented with a persistent dry cough for roughly six weeks that was not improving despite medical treatment. Computed tomography (CT) imaging showed a right-sided aortic arch, and over several years, it progressively continued to compress the patient's trachea, which was confirmed via bronchoscopy. This case emphasizes the importance of considering anatomical anomalies in patients with unexplained chronic cough and emphasizes the necessity for collaboration among medical specialties to evaluate and treat this rare presentation.
