When a rib fracture heals, the callus formation may create a mass-like appearance (blue arrow). Sometimes a CT is necessary to differentiate a healing fracture from a lung mass. Notice the large lung volume and the enlarged pulmonary vessels. Probably we are dealing with pulmonary arterial hypertension in a patient with COPD. #Clinical #Radiology #CXR #Old #RibFracture #Callus #Pseudotumor #RadiologyAssistant
