LUNG - Trauma

The cut surface shows a number of haemorrhagic areas in the lung substance where the lung appears more or less intact. In the lower part there is a large irregular wedge of blood clot extending to the diaphragmatic surface with further evidence of damage close by. The pleural surface shows a number of haemorrhagic adhesions.
The wheel of a horse-drawn cart passed over this woman's chest. She survived 12 days. At autopsy one lung showed multiple cystic cavities containing brown fluid, presumably resulting from trauma. The histology showed bronchopneumonia, infarction, haemorrhage and areas of organising pneumonia with overall appearance of 'shock lung'.
