Meanings of pulmonary interstitium in English

A larger proportion of severe patients showed reticular pulmonary interstitium thickening.

In patients with UIP, more active inflammation of the pulmonary interstitium results in faster progression of honeycombing in long-term follow-up.

The course of the disease is often indolent with some patients eventually dying of respiratory failure secondary to progressive tumor infiltration of the pulmonary interstitium.
