Common non-cardiogenic causes include inflammation in the lungs or system-wide inflammation which causes the pulmonary capillaries to be more permeable.

Lymphatic capillaries are extremely permeable because their walls are made of endothelial cells that only loosely overlap, forming one-way minivalves.
