Chest radiograph findings in anomalous pulmonary venous drainage- Focal mediastinal widening to the left of the aortic knob. a Patient 1. Postero-anterior (PA) chest radiograph (CXR). Vascular shadow adjacent to the aortic knuckle corresponds to anomalous left superior pulmonary vein (LSPV) in (b). b Coronal maximum intensity projections (MIP) CT image demonstrating anomalous LSPV (black arrow) draining into the brachiocephalic vein (LBCV). This is the most common left sided partial anomalous pulmonary venous drainage pattern. c Patient 2. Posteroanterior chest radiography. The LSPV can be seen as a prominent vascular shadow lateral to the aortic knuckle and left subclavian artery (black arrow). d Coronal MIP MR angiography demonstrating LSPV (arrow) draining into the left BCV (LBCV)
