Figure 1: (a) Coronal oblique thick multi-planar reconstruction (MPR) of computed tomography angiogram (CTA). This reveals the right- and left-sided pulmonary veins (RPV and LPV, respectively) joining together to form a descending common chamber (*) to the left of the thoracic aorta (Ao). Increased attenuation along bronchovascular bundles in both lungs is consistent with pulmonary edema. (b) Zoomed-up view of a thin MPR in the same plane shows stenoses at two sites in the common chamber (*). The first obstruction (white arrow) is followed by a dilatation (white arrowhed). The second narrowing (white arrow) is at the site of drainage into azygos vein (Az)
