Although lung torsion would not explain a lung
being fatty I was curious about potential causes when
I was asked off-line if the ferret may have been dropped.
I don't know that a typical dropping injury could do that,
but I honestly don't know. The ribs provide a lot of
protection normally.
What I found on the web on cats, dogs and humans
indicated that some individuals have congenital
(birth defects) that cause either strange positioning of
a lung, or strange dispersal of blood vessels.
Compression injury has been seen as a cause. For adult
humans the most common cause mentioned was it being
secondary to chest surgery due to placement or other
change.
Knowing this still would not explain the fatty part at all
so it could easily not be applicable; the explanation
would need to take in both components.
Ah! I just came upon a cite with an outstanding summary:

BEGIN QUOTE
Lung lobe torsion (LLT) results from a displacement and
twisting of a lung lobe around its bronchovascular pedicle.
This relatively rare disorder affects dogs, cats, and humans.
Etiologies include primary (i.e., spontaneous) and secondary
torsion due to thoracic trauma, pleural space disease, thoracic
surgery, pulmonary parenchyma disease, and diaphragmatic
hernia repair.

Like I said, though, the cause needs to explain the fatty
component and this doesn't...
Please, if you can transcribe in the results of the histopathology
report later that would help teach all of us so that ferrets will
be safer.
