Acute fibrinous pleuritis, postmortem, cow

    Postmortem photograph of the lung of a cow that died due to acute fibrinous pleuritis associated with inhalation pneumonia. Upon necropsy examination of thoracic cavity, several liters of fibrinous pleural fluid were present. The lungs did not inflate and samples sink in formalin. The lung tissue is also malodorous, consistent with a mixed aerobic and anaerobic bacterial infection due to aspiration of rumen contents.
