The widespread use of multidetector computed tomography (CT) in clinical practice has resulted in incidental detection of several variations of the aortic arch in adults.

Understanding the embryological development of the aortic arch aids in the classification of various subtypes of aortic arch anomalies and variants.

Transthoracic echocardiography (TTE) revealed a dilated pulmonary artery (PA) and a left to right shunt between the descending thoracic aorta and PA (peak velocity 4.5 m/s, Figure 1A and B), suggesting the presence of a patent ductus arteriosus (PDA). Chest computed tomography (CT) revealed multiple consolidations in both lungs, suspicious of embolic pneumonia (Figure 1C). Streptococcus sanguinis was isolated from 2 sets of blood cultures. The patient underwent transesophageal echocardiography (TEE), which revealed hypermobile linear materials in the PA (Figure 1D-F). On heart CT, a PDA at the end of the aorta (8.5 mm in size), calcification of the ostium, and abutting aorta were detected (Figure 1G). On 2-dimensional (2D) and 3D CT, images clearly showed an ill-defined nodular lesion (0.6 cm) attached to the medial side of the main PA (Figure 1H and I). The patient was diagnosed with a PDA accompanied by infectious endarteritis and septic embolic pneumonia. A combination of gentamicin (3 mg/kg daily) and intravenous ceftriaxone (2 g daily) was initiated.
