This is a nice simple case that I thought had some good teaching points.
36 yo male with fever, cough, history of anxiety. Here is the initial CXR:
#FOAMed #FOAMrad This is classic lobar pneumonia, involving the right upper lobe. Sometimes pna can look mass like on one of the views, but often the other view shows it spreading out along a fissure or other pleural boundary, fading along the non pleural margin, more typical of pna than cancer.

If report CT chest, this is an important entity to know about. This is a very good example of it. Not quite middle-aged male with chest pain and fever, no other medical history.
What is your diagnosis?

@JeffreyKanneMD @CsFuss Here are the lung windows, showing pretty typical right lower lobe pneumonia. Does this change your thinking about the first image? Note that there is no interstitial edema in the RLL or pleural effusion.

Here is a gorgeous case of CTD-ILD. I found this whole entity very confusing at first. I’ll show images at presentation, 7 days, 2 months, and 6 months. I’ll also share PFTs, BAL, serology, and path report. Please comment on these if you like. #FOAMed #FOAMrad #radres 1/ The patient is a 45 yo male. Acute kidney injury and ? Pneumonia. The first image was at presentation. There is peribronchial consolidation with a nice perilobular appearance peripherally. Looks like organising pna. Cause could be infection, vaping, drug reaction, CTD...
