Lung contusion. Axial (a, b) and coronal (c) CT images at lung window show nodular opacities of ground-glass opacity that do not respect the lung boundaries of the right upper lobe (white arrows) (a), diffuse areas of ground-glass opacity in the upper lobes bilaterally with subpleural sparing (white arrows) (b) and multiple areas of consolidation with air bronchograms (white arrows) and small lacerations (black arrows) in both lungs consistent with lung contusions. Note small bilateral pneumothorax in both lung apices (black dotted arrows) and cardiophrenic angles (black dotted arrows) (c)
