Abstract

DiGeorge syndrome is a rare spectrum of disorder affecting structures derived from third and fourth pharyngeal pouches characterised by aplasia or hypoplasia of thymus and parathyroid glands, and conotruncal anomalies. Presentation includes infants with hypocalcemic seizures, CHD, or recurrent infection. This case report illustrates a unique combination of proximal interruption of right pulmonary artery and aberrant right subclavian artery in a 3-month-old infant who was subsequently diagnosed as DiGeorge syndrome. This constellation of vascular anomalies in an infant with DiGeorge syndrome has not been previously reported in the literature.
