case_images: It also interestingly showed evidence of multiple collateral flows at the os of the left superior PV with a peak velocity of the predominant flow of 45 cm/s (Figure 1).
case_images: Lung V/Q scan showing absent perfusion of the left upper pulmonary lobe and lingula (arrows) based on the comparison of the relatively (a) normal ventilation to the (b) abnormal perfusion in the left posterior oblique (LPO), left anterior oblique (LAO), and left lateral (L lat.) projections.

case_images: Coronal oblique view (a), axial view (b), and volume-rendered 3D reconstruction (c) from an arterial phase CT angiogram demonstrate absence or stump of the left superior pulmonary vein (white arrows) and left upper lobe oligemia ((c), circled) and chronic interstitial edema ((b), circled). Coronal oblique vascular reconstruction from a delayed venous phase CT angiogram (d) demonstrates small collateral draining veins (yellow arrows). LULL = left upper lung lobe.
