Also known as ‘acute respiratory distress syndrome’, this is an acute condition characterised by bilateral pulmonary infiltrates and severe hypoxaemia in the absence of cardiogenic pulmonary oedema. The underlying problem is diffuse alveolar damage.
PLAIN FILM
•  Normal for the first 24 hours, then septal lines and peribronchial cuffing, but no effusions.
•  Unlike pulmonary oedema, infiltrates are initially peripheral rather than central, and air bronchograms are more commonly seen.
•  May be complicated by pneumonia.
HIGH-RESOLUTION CT (HRCT)
•  After months, the consolidative pattern gives way to reticulation in the non-dependent lung and, finally, honeycombing.
