From: Anomalous pulmonary venous drainage: a pictorial essay with a CT focus
Anomalous left superior pulmonary vein (LSPV) may mimic a left sided superior vena cava (SVC) on axial CT images. Patient 1. Bilateral SVCs with anomalous left SVC draining into the left atrium (a and b). a Bilateral SVCs. Right SVC (arrowhead) and small left sided SVC (white arrow). b Coronal MIP CT in the same patient showing the anomalous left SVC draining into the left atrium (white arrow). Normal right-sided SVC (thin white arrow). Patient 2. Partial anomalous pulmonary venous drainage (c and d). c Anomalous LSPV (white arrow), which on single axial slice is similar in appearance to the left-sided SVC in (a). d Coronal MIP CT showing the anomalous LSPV (white arrow) draining into the left brachiocephalic vein (LBCV). Normal right SVC (thin white arrow)
