- reversible injury is accumulation of fat / steatosis or bilirubin
- inflammation due to changes in environment (cells swell and
leak)
liver injury - irreversible injury is necrosis or apoptosis
(hepatitis is formation of apoptotic bodies)
- chronic injury and inflammation leads to cirrhosis scarring
- this can be reduced if the injury is resolved but is all happening
at the same time
- gross appearance changes very little and appears
slightly mottled due to cell death
acute liver disease - can shrink slightly
- monocyte infiltrate but minimal inflammation
- cell death occurs due to apoptosis or necrosis
- gross appearance shows an enlarged liver with
cirrhotic nodules and colour or consistency changes
due to intracellular accumulation of fat
chronic liver disease
- significant inflammation and monocyte infiltration
- fibrosis and scarring
- fat accumulation and cellular swelling
- cell death
- common include viral hepatitis, or non viral
- non alcoholic fatty liver
- alcoholic fatty liver disease
- less common is autoimmune
- Wilsons disease
liver diseases
- haemochromatosis
- cholestasis (stop in flow of bile)
- consequences of portal hypertension, liver failure,
cirrhosis (no going back), jaundice
