consolidation
Pronunciation: kon-sol-ih-DAY-shun
Radiographic finding showing dense opacity in lung tissue, typically indicating pneumonia or other pulmonary pathology.
Full Definition
Consolidation refers to a radiographic pattern seen on chest imaging where normal air-filled alveolar spaces are replaced by inflammatory exudate, cells, or other material, resulting in increased density on chest radiographs or CT scans. In pediatric infectious disease, consolidation most commonly indicates bacterial pneumonia, though viral pneumonias can occasionally cause focal consolidation. The finding appears as a homogeneous opacity that obscures normal lung markings and may contain air bronchograms. Location, extent, and associated findings help differentiate bacterial from viral etiologies and guide antibiotic decision-making. Multi-lobar consolidation or rapidly progressive disease may indicate more severe infection requiring aggressive treatment.
Usage
Usage note: Distinguish from other radiographic patterns like infiltrates or atelectasis; specify anatomical location.
