1. Pulmonary edema
2. Pneumonia
3. Aspiration
4. Hemorrhage
this means presence of fluid inside alveoli which could be water as in pulmonary edema,exudate in pneumonia,blood in hemorrhage or any kind of aspiration materials.
1) Pulmonary Alveolar Edema. There is extensive, bilateral airspaces disease with fluid in the minor fissure (blue arrow) and bilateral pleural effusions (ref arrows). Although the heart is not enlarged, the cause was still on a cardiogenic basis.http://www.google.com.eg/imgres?imgurl=http://www.learningradiology.com/caseofweek/caseoftheweekpix2007-1/cow267arr.jpg&imgrefurl=http://www.learningradiology.com/archives2007/COW%2520267-Pulmonary%2520edema-CHF/pulmedemacorrect.html&usg=__YRtgi0C8v73xQys3usyMs9_3_Vw=&h=443&w=500&sz=38&hl=en&start=8&sig2=GWET39uAxZAeo7LW_hF9VQ&itbs=1&tbnid=DIXYRi9W8kwI2M:&tbnh=115&tbnw=130&prev=/images%3Fq%3Dpulmonary%2Bedema%2Bx%2Bray%26hl%3Den%26sa%3DG%26gbv%3D2%26tbs%3Disch:1&ei=nHMwTNOmOMuTjAfIjbHDBQ

3) aspiration pneumonia:Ninety percent of unilateral diffuse lung opacities are accounted for by just five conditions: pneumonia; aspiration; pulmonary oedema; lymphangitis; and radiation pneumonitis.
4)pulmonary hemorrhage:chest radiographs demonstrate extensive bilateral diffuse pulmonary consolidation with sparing of the periphery of the lungs, creating the window frame effect that is suggestive of pulmonary hemorrhage.
