Radiology Question about Pneumonias...?

Question

Hi! To any Radiologist/Medical ppl - can you give me a quick heads up on

1) How Community acquired pneumonia looks on CXR? (I think its normally lobular right?) - any other details/ aspects of specific types of CAP?

2) What does Atypical pnemonias look like, eg - PCP, etc....

I am looking for trends just to clarrify, I realise there is always exceptions, any answers (apart from ppl who dont know telling me to look it up) is appreciated, thanks in advance...

Answer 1

CAP can have variable presentation on radiography, although classically it appears as a region of increased opacity without volume loss.

Atypical pneumonias also have variability in their radiographic appearances, but generally to not conform to the consolidative pattern of CAPs.  A common appearance for Mycoplasma or PCP is that of reticolonodular, diffuse opacity.
