"Primary pulmonary disease where diffuse cysts are the predominant feature:"
"Acquired cystic lung disease or cysts as a secondary feature of a primary disease:"

Expected headings
"Radiographic appearance"
"CT"
"Cystic lung disease is an umbrella term for diseases that exhibit thin-walled lung cysts on CT. This distinguishes them from emphysema (no walls) and cavities (thick walls). The underlying pathogenesis is diverse including neoplastic, genetic and inflammatory."
"pneumocystis pneumonia: diffuse ground glass opacities with few cysts, septal thickening, in patients with immunodeficiency (e.g. HIV/AIDS)"
