Not including larger pulmonary vessels (instead summarized at Autopsy - Other thorax).
Contents
Basic autopsy cutting
In non-forensic Autopsy:
- Dissect the pulmonary arterial system, from the pulmonary trunk and including at least segmental arteries.
- Dissect the bronchial tree, at least to segmental bronchi. Check for obstructions.
- Make some additional sections through the lung parenchyma. Squeeze at each side to detect any pus and edema.[1]
Further information: Autopsy
Gross evaluation
- A spongy consistency, and watery and frothy liquid being pressed from the parenchyma, indicates simple edema.[2]
- A spongy consistency and reddish (blood-stained) fluid being pressed from the parenchyma, indicates acute congestion.[2]
- A brownish or dark reddish color of the fluid pressed from the parenchyma indicates chronic congestion, and may not have a spongy consistency.[2]
Fixation
Generally 10% neutral buffered formalin.

Microscopic evaluation
Look for the most common pathologic lung findings:[3][4]
- Edema and congestion (often together), indicating left sided heart failure:
- Pneumonia: Inflammatory cells
- Tuberculosis in regions of the world with substantial prevalence
- Carcinoma
- Aspiration: Other foreign contents in airways.
Edema
Bronchopneumonia, with neutrophils filling a bronchiole.
Reporting
Report findings and if they are consistent with already known diagnoses. Further information: Autopsy
