My 14 year old male, neutered Brittany had an emergency splenectomy last year. Thankfully, the biopsy came back as a benign. A day prior to his surgery he had an abdominal ultrasound which also indicated a small (1 inch) tumor on his liver. The vet preforming his splenectomy did not have the equipment neccessary to take a biopsy of the liver while he was on the table. His liver enzymes have been elevated over the past year (100-200 above normal), and he is on Denamarin. In the past two weeks he has had two seizure-like episodes, which quickly resolve in under 5 minutes. Radiographs done a few days ago showed that he has a large abdominal mass that is displacing his intestines laterally (as well as cranially, not caudally which makes me think it is not originating in the liver). He has surgery to remove two large lipomas last year, and my vet believes this abdominal tumor is (hopefully) just a large internal lipoma. I am planning on doing a laproscopic liver biopsy in the next week. My question is, does he need an abdominal ultrasound to get a picture of the abdominal mass before the liver biopsy? Should a laproscopic biopsy be done of this abdominal tumor, at the same time as the liver biopsy? He has had two surgeries in two years, and I am concerned about opening him up again for abdominal exploratory surgery.
