Bilateral perihilar haze, prominent upper pulmonary veins, diffuse alveolar (ill-defined opacities) and interstitial oedema (Kerley B lines in the basal lung zones - see key image). Prominent horizontal fissure suggesting a small pleural effusion on the right.
The patient demonstrated classic features of pulmonary oedema including the bat's wing appearance of the hila, alveolar and insterstitial oedema, upper lobe venous diversion, and a small amount of pleural effusion.
Consequent urgent echocardiography demonstrated an akinetic ventricular septum, decreased left ventricular function, and moderate mitral valve insufficiency. Considering all this the pulmonary oedema was caused by the ongoing acute myocardial infarction whilst considering the elevated CRP an overlapping inflammatory component cannot be ruled out.
