Below is the chest Xray of a young male with cough. There is no known cardiac abnormality. With of the following is most likely to be true about the patient? 
Select and explain. 
A. Raised ACE levels likely, B. Patient is likely to be immunocompromised, C. Cold agglutinins will be positive, D. Occupational history of patient will give an important clue to the diagnosis
B: Patient is likely to be immunocompromised
Answer: B: Patient is likely to be immunocompromised 
Explanation: Ans. B. Patient is likely to be immunocompromised* Its typical bilateral perihilar consolidation and Reticulo nodular interstitial involvement, typical of PCP.* Mycoplasma infection not likely as mycoplasma radiographically produces fluffy opacities and those infiltrations of mycoplasma are not Perihilar. It is not likely to be sarcoidosis, as there is no hilar adenopathy (the shadows near hilum seen parenchymal perihilar opacities).* IN a young boy, generally no occupation causes such ILD or a DLD, so occupational details may not help much.
