The role of chest radiographs in the follow-up of acute respiratory distress syndrome (ARDS). a) The serial evaluation of chest radiographs in ARDS and right pneumothorax (black arrow), b) allows the early detection of a left pneumothorax (white arrow) and the increase of the known right pneumothorax.

Radiological evolution of acute respiratory distress syndrome over the first week in a 57-year-old male with non-Hodgkin’s lymphoma and H1N1 infection. a) On admission the radiography examination did not show any pathological findings. b) The next day some pulmonary consolidations appeared at the lower lobes. c, d) Over the next 2–3 days, a rapid deterioration of clinical and radiological conditions occurred with consolidations (c) progressing to diffuse alveolar involvement, with “white lung” appearance (d). The normal-sized heart and vascular structures help in the differential diagnosis of pulmonary oedema due to heart failure.

Typical computed tomography features of acute respiratory distress syndrome showing: non-homogeneous distribution, a ventro-dorsal gradient of density, more dense consolidation in the dependent regions, widespread ground-glass opacities associated with thickening of interlobular septa (crazy paving), and pleural effusion.

Long-term evolution of acute respiratory distress syndrome. a, b) Computed tomography scan performed at admission demonstrated multiple and bilateral ground-glass opacities, which were inhomogeneous in distribution. c, d) After 2 months of recovery an advanced stage of pulmonary fibrosis could be detected, with honeycombing and bronchiectasis, which are more evident in the anterior lung regions.
