- Larynx appeared normal.
- Mucosa of trachea, major and minor bronchi was reddened with overlying pus.
- The lungs weighed 1000g (r) and 800g (l).
- Both lower lobes showed extensive consolidation with pus in the parenchyma and focal abscess formation; the slice you take shows a very consolidated section of the right lower lobe (see image below - left).
- The upper lobes were emphysematous - a common finding in COAD. In addition, there were areas of mild parenchymal destruction and surface blebs. In addition, patchy areas of consolidation were noted in both upper lobes.
- No evidence of pulmonary embolism, infarction or tumour.
Both pleural cavities contained numerous fibrous and fibrinous adhesions but no effusions.
- Microscopy; the image below (on the right) is a low-power microscope image of a piece of the right lower lobe. The alveoli on the left-hand-side are full of exudate, preventing gaseous exchange within the tissue. There is a fairly well-defined border between those alveoli and those on the right, which appear relatively unaffected.
