Consolidation Flashcards
What is consolidation
Filling of the alveolus with obscuration of the pulmonary vessels. The bronchus is visible as an air bronchogram
Consolidation is histologically due to the complete filling of the affected alveoli with a liquid-like substance that can include?
1) blood
2) pus
3) water
4) cells
Air bronchograms are often present in consolidation if
the airway is patent
Differential Diagnosis of Acute Consolidation
(PPP)
-Pneumonia (by far the most common cause of acute consolidation)
-Pulmonary hemorrhage (primary pulmonary hemorrhage or aspiration of hemorrhage)
-Pulmonary Edema
-Acute respiratory distress syndrome (ARDS) which is
noncardiogenic pulmonary edema seen in critically ill
patients and through to be due to increased capillary
permeability
-Heart Failure
Differential Diagnosis of Chronic Consolidation
BOC
- Bronchioloalveolar carcinoma mucinous subtype, a form of adenocarcinoma
- Organizing pneumonia, which is a nonspecific response to injury characterized by granulation polyps which fill the distal airways, producing peripheral rounded and nodular consolidation
- Chronic eosinophilic pneumonia an inflammatory process characterized by eosinophils causing alveolar filling in an upper lobe distribution
