Q

What is this?

A

Microvesicular fatty
infiltration
(steatohepatopathy)

white things are empty holes not fat droplets as the fat is dissolved in preparation of the slide but used to have fat in them

Q

What is this?

A

Macrovesicular fatty
infiltration
(steatohepatopathy)

more severe form

uneven distribution of fat droplets

cental lobular areas contain most fat around central vein

Think of species fatty liver e.g cows post calving decreased energy mobilisation ketosis + fois grais and dog and cat hepatic lipidosis
