The retracted visceral pleura is seen which indicates that there is a pneumothorax.
There is a horizontal line visible.
Normally there are no straight lines in the human body unless when there is an air-fluid level.
This means that there is a hydro-pneumothorax.
When a pneumothorax is small, this air-fluid level can be the only key to the diagnosis of a pneumothorax. #Clinical #Radiology #CXR #Pneumothorax #Hydropneumothorax #RadiologyAssistant
