Case Discussion

PAPVD is due to drainage of pulmonary veins into SVC, IVC or coronary sinus, creating a left to right shunt, in this case, only right upper lobe demonstrating anomalous drainage. Because of relatively small size of the shunt, this patient was not symptomatic, and presented with unrelated symptoms.
