27. Lobar pneumonia

Organ: Lung

Description:

We can see two lobes of a lung. The upper lobe is healthy and shows no alteration. The lower lobe is greyish and appears denser than the upper lobe. Anthracosis is visible everywhere in the lung.

Diagnosis: Lobar pneumonia

Causes:

See theoretical topics

Theory:

In lobar pneumonia is only one lobe affected. The affected lobe is diffusely affected (meaning the whole lobe is inflamed). Compare this to the bronchopneumonia preparation.

If we could touch the affected lobe would we notice that it’s firmer than the healthy lobe. In fact, it resembles the consistency of the liver, which is why this characteristic is called hepatisation.
