We found quite a few things. First, although we do not have the tooth age on it, we estimate that it is an old animal. This is based on body size, external marks, tooth wear, and constellation of disease findings. There was evidence of recent and rapid weight loss. It had many old or chronic lesions.
Serosal adhesions result from inflammation in the past, now scarred and inactive.
Hydrocephalus can be either externa or interna. Hydrocephalus externa is too much fluid around the brain, usually resulting from brain injury or shrinkage. This allows normal circulation of the fluid. This results in a pressure buildup inside the ventricles, which in turn interferes with blood flow through the fine vessels of the brain. As a result the brain atrophies or shrinks from the inside out.
