(A–C) Right lateral projections of a traumatized dog showing changes over time of lung lacerations. (A) On admission, an alveolar pattern was noted in the middle lobe area (circle) surrounded by a diffuse interstitial pattern. (B) Two days later, in the same area (circle) a large ovoid lesion with hydroaeric level was noted (pneumohematocele). (C) Four days after admission, in the same area (circle) the lesion was clearly visible (hematocele); another small lesion, with air–fluid levels, was noted.
