Er, 'fraid not. Freezing is going to substantially change the appearance of all the tissues so that many types of pathology will no longer be apparant. As an example, if you open a fresh specimen and see red, raw looking lungs with liquid in them, you have a huge clue as to what happened to the animal. If you open a frozen specimen and see the same thing, that tells you absolutely nothing. That's just what happens when you freeze that tissue.
Some types of discolorations in other internal organs will survive freezing, others will not. Freezing can produce discolorations that can superficially resemble pathologies.
If you are looking for evidence of parasites, forget it - the freezer turns all that to mush on a microscopic level. Similarly it blasts all the cells and breaks them, the blood, the cells making up the internal organs, everything. So if you wanted to look at the blood count or a section of an organ under the 'scope to check for inclusions, microabscesses, trauma, etc, you're out of luck on a frozen specimen.
Lucky for you the main question here is the nutritional status of this animal, and you will be able to determine that on gross pathology even on a frozen animal.
