A chest radiograph showed a left perihilar density, which was suspicious for a left-sided pulmonary arteriovenous malformation (PAVM) [Figure 1].
(a) Coronal image. Single pulmonary vein (arrowhead) crosses the midline superior to the left atrium to join a vessel in the left lung. Single pulmonary vein joins the left atrium (arrow). (b) Transverse image. Single pulmonary vein joining the left atrium. (c) Transverse image. Pulmonary vein crosses midline. (d) 3D image. The course of the common pulmonary vein. LPA - Left pulmonary artery; RPA - Right pulmonary artery; RSPV - Right superior pulmonary vein; RIPV - Right inferior pulmonary vein; CPV - Common pulmonary vein; CRT - Common right trunk; LA - Left atrium

A chest CT scan with contrast and 3D reconstruction revealed an extensive pulmonary vein abnormality [Figure 2].
Pulmonary artery wedge injections in the right upper lobe pulmonary artery (a), right lower lobe pulmonary artery (b), left upper lobe pulmonary artery (c), and left lower lobe pulmonary artery (d), demonstrating the course of the individual pulmonary veins. A coil can be seen in the ductus arteriosus (small arrow)
