Pathological changes of the lung

Examination of the respiratory system showed the presence of fluid inside the trachea
and bronchi. The fluid was yellowish in colour and not sticky. The cut section of the

lung infection showed dark colour and was consolidated. It had an unhealthy
appearance compared to a normal lung. The cut section of lung also showed presence
of mucus plugs inside the small airways.

Histology of the lung showed a hyaline membrane formation consistent with diffuse
alveolar damage. High power histological examination showed the presence of

cytopathology effect of viral pneumonia of the lung tissues. And, in some areas, there
were superimposed bacterial infection where we could see a lot of neutrophil
infiltration in the lung tissues.

From our post-mortem finding we did not detect any thrombus inside the vessels.
