Even allowing for the AP projection, the cardiac silhouette is enlarged. Small bilateral pleural effusions.
Bilateral perihilar consolidation/airspace change with a "bat wing" appearance.
Case Discussion

It typically occurs when pulmonary wedge pressures are high. It is one of the core plain radiograph features of cardiac failure.
