Description

It is very important to differentiate between acute consolidation and chronic consolidation, because it will limit the differential diagnosis.
In chronic disease we think of:
 - Neoplasm with lobar or segmental post-obstructive pneumonia.
 - Lung neoplasms like bronchoalveolar carcinoma and lymphoma.
 - Chronic post-infection diseases like organizing pneumonia (OP) or chronic eosinophilic pneumonia, which both present with multiple peripheral consolidations.
 - Sarcoidosis is the great mimicker and sometimes the granulomatous noduli are so small and diffuse that they can present as consolidation.
This is known as alveolar sarcoidosis.
 - Alveolar proteinosis is a rare chronic disease that is characterized by filling of the alveoli with proteinaceous material. #Diagnosis #Radiology #Pulmonary #CXR #Consolidation #Acute #Chronic #Differential #RadiologyAssistant
