Anal sac mass noticed during examination, bloods show mild hypercalcaemia. CT scan with contrast performed and the report can be seen here . It is a colleague&#39;s case, anden-USTelligent Community 10https://www.vetsurgeon.org/thread/154510?ContentTypeID=1Thu, 10 Mar 2016 09:12:28 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:dce80cd6-74bb-4b30-9e72-6cb821fcfe39Rob Davis<p>Many thanks (again!)

I agree that the lymph node is metastatic and that the splenic changes are very unlikely to be metastases. However, it would be wrong to undertake surgery without first demonstrating that the splenic changes are indeed benign. Likely success and costs of surgery at your hospital are things I am unable to comment upon. However, if this case presented to me I would be likely to recommend surgery with serial re-evaluations on a quarterly basis thereafter. I would expect further lymph node metastasis to develop within twelve months of surgery. I would expect hypercalcaemia to resolve in response to surgery if that was a real observation in the first place. Please note that hypercalcaemia increases the risk of death during and immediately (3d) after surgery due to alterations in tissue perfusion and coagulopathy effects.</p> <p>Best wishes</p> <p>Gerry</p><div style="clear:both;"></div>
