Unilateral pulmonary oedema represent only 2% of cardiogenic pulmonary oedema with predilection for the right upper lobe and is strongly associated with severe mitral regurgitation ^{1, 2}. It is hypothesised that the regurgitation jet is directed towards the right superior pulmonary vein thus preferentially increasing the hydrostatic pressure in the right upper lobe ³.

Pathology

Aetiology

Unilateral oedema with ipsilateral pathology ⁴:

severe mitral valve regurgitation
positioning
re-expansion pulmonary oedema
pulmonary vein occlusion
congenital or surgical right-to-left shunt (e.g. Blalock-Taussig shunt)

Unilateral oedema with perfusion abnormality in the contralateral lung ⁴:

unilateral pulmonary embolism
unilateral hypoplasia of pulmonary artery
Swyer-James syndrome
unilateral emphysema/bullae
