General patho check-list
Use this when you see the lesion
- Post mortem changes
- Circlatory changes - Blood, Oedema
- Regressive changes - necrosis, fat infiltration
- Prolifferative changes - Collagen, Fibers
- Inflamation
- Tumours
- Development anormalies
Liquid could be, and from lesion?
- Serous
- Purulent
- Sero-mucus
- Muco-purulent
- Sero-sanguineus fluid - ‘Like blood’
From Lesion
* Purulent
* Ichorous
* Caseous (dry)
* Tumour necrosis
Exudate, Modified, Transudate?
LUNGS
Patological findings (types)
1. Consolidated lung
* Darker
* Firmer
* No crepitation
* Atelactatic
2. Emphysematous lung
* Paler
* More creppitation
3. Congested (CS) lung
* Blood flow on the surface
LUNGS
Tumours found in the lung could be
Mesothelioma –> Visceral plaura
LUNGS
Types of pneumonia
- Bronchopneumonia
- Interstitial pneumonia
- Metastatic pneumonia
- Aspiration pneumonia
- Pulmonary oedema
LUNGS
Bronchopneumonia
1. Which lobes
2. Types
3. Appearance
4. Shape, Size, Colour, Consistency
BRONCHOPNEUMONIA
1. Cranio-ventral lung lobes
2.
Purulent (pasteurella)
Acute - Hyperaemic
Chronic - Fish meat like
* Cattarhal*
* Fibrinous - Bronchoalveolar junction
3. Mottled appearance?
Darker, lighter area
Multifocal purulent coalescing nodules - PURULENT
- Shape, Size = ENLARGED, Colour,
* Consistency
Cattarhal = Gland like
Fibrinous = Liver like + Fibrinous accumulation
LUNG
Interstitial pneumonia
- Dark purple
- Bacteria from CT
- Not in airways - Check bronchus
- Abcess in parenchyma
- Muscle flacid palpation
- Rubbery - Enlarged lungs not colapsed - rib imprints
Heavy/Wet lung
LUNGS
Metastatic pneumonia
- Cranio-ventral lunglobes
- Foci will be everywhere - No parenchyma palpation
- (Piglet if canibalism - Ear and tail biting)
LUNGS
Pulmonary Edema
- Foam in trachea + Bronchi
- Difuse congestion + Atelactasia
LUNGS
Aspiration pneumonia - Where do we find it
Right middle lobe
LUNG
