RESUMEN
The pulmonary veins normally drain into the left atrium, with the superior pulmonary veins typically situated anterior and inferior to the right pulmonary arteries. However, anomalies can happen. We encountered an exceedingly rare pulmonary vascular anomaly for a patient presenting with atypical chest pain, where the right superior pulmonary vein aberrantly ran posterior to the right pulmonary artery (RPA) and became compressed between the RPA and the right main bronchus. Coronary computed tomography angiography identified this specific pulmonary vein anomaly but revealed unremarkable coronary arteries.

Coronary arteries normally originate from two separate cusps from the aorta, and various anomalies can occur. One such anomaly is the single coronary artery (SCA), where the coronary arteries originate from a single ostium due to the absence of the contralateral ostia. In a rare case we encountered while evaluating a patient with atypical chest pain, computed tomography angiography revealed that the right ostia was absent, and the right coronary artery originated from the left circumflex artery. This subtype of SCA has been exceedingly rare, with only a few cases reported in the literature.
