Dear friends, I am starting a new webinar series entitled “Things that we already know, but are important to remember”. The objective is to refresh basic concepts that often are forgotten.
This week’s webinar title is “Who is afraid of the bad, big lateral chest”. The webinar will take place on Wednesday, September 30 at 12:00 CEST. You can register here.
The initial case is a PA chest radiograph of a 61-year-old man with hemoptysis.
Do you see any abnormality?
1. Yes
2. No
3. I want a lateral chest
Register for the webinar and lear more about this case and others!

Findings: PA radiograph (A) does not show any significant findings. The lateral view shows a posterior pulmonary nodule with irregular contour (B, arrow). A typical donut sign is visible (B, circle), indicative of enlarged subcarinal lymph nodes.
Enhanced axial CT and PET-CT show confirm the pulmonary nodule (C-D, arrows) and the subcarinal lymphadenopathies (C-D, red arrows).
Final diagnosis:
Carcinoma hidden in the PA view behind the right hilum with metastases to subcarinal lymph nodes.
Congratulations to drpeca who was the first to want a lateral view.
Teaching point: remember that about 26% of the lung is hidden in the PA view. A lateral chest radiograph is indispensable to study the chest.
