Case in brief
A 4-year-old boy with recurrent respiratory infections underwent cardiac CT, which showed tetralogy of Fallot with a subaortic ventricular septal defect, overriding aorta, right ventricular hypertrophy, and right ventricular outflow tract narrowing. The pulmonary valve was dysplastic, and the main and branch pulmonary arteries were markedly aneurysmally dilated, compressing the right main bronchus. CT provided a comprehensive anatomical assessment relevant to preoperative planning.
What made this case unusual
The aneurysmally dilated pulmonary arteries compressed the right main bronchus, providing an anatomical explanation for the child’s recurrent respiratory infections.
Diagnostic / clinical pearl
In a child with tetralogy of Fallot and recurrent respiratory infections, cardiac CT can delineate pulmonary artery enlargement and its relationship to the airways, as well as the associated cardiac anatomy.
