Idiopathic pleuroparenchymal fibroelastosis is a rare condition that is classified as an idiopathic interstitial pneumonia.

Men and women are affected about evenly. Idiopathic pleuroparenchymal fibroelastosis occurs in people of all ages. However, the median age when the disease starts is around 57 years. Most affected people are nonsmokers.

Diagnosis of idiopathic pleuroparenchymal fibroelastosis requires chest computed tomography (CT). Sometimes a biopsy of the lung is needed to confirm the diagnosis.
The appropriate treatment for this condition is unknown. Sometimes doctors give corticosteroids because they are effective in some of the other idiopathic interstitial pneumonias, but their effectiveness in idiopathic pleuroparenchymal fibroelastosis is unknown.
