Pneumonia (1418/1700)

A 49yo man comes with hx of cough and SOB. His CD4 count is measured as 350. CXR shows lobar consolidation. What is the single most appropriate option?

a. Mycobacterium avium intercellular
b. CMV
c. Streptococcus
d. Toxoplasmosis
e. Pneumocystis jerovici
































answer: C

Strep pneumonia is associated with immunosuppression and has a lobar pattern, the only other real contender here is Pneumocystitis (the others can be excluded w/o knowing them because you will not be expected to be able to differentiate their pneumonias at PLAB level), we can exclude it because in pneumocystitis there will be perihilar shadowing or nothing at all.

This is the page in OHCM from which all these PLAB pneumonia questions are written:

    Here CD count >350 so it is pneumococcal pneumonia but if CD count <200 so it is pnemocystis jerovici
