Consolidation is synonymous with airspace disease. When you think of the causes of consolidation, think of 'what is replacing the air in the alveoli'? Is it pus, edema, blood or tumor cells (Table on the left). Even fibrosis as in UIP, NSIP and long standing sarcoidosis can replace the air in the alveoli and cause consolidation. #Diagnosis #Radiology #Pulmonary #CTChest #Consolidation #Differential #RadiologyAssistant
