- 12 year old mn DSH with history of weight loss despite good appetite
- Owner feeds cat by hand in small amounts and does not keep track of how much :(.
- Recently diagnosed with hyperthyroidism (T4=7.0) but is well controlled on methimazole (T=1.5).
- Bloodwork and radiographs were nonremarkable.
- Abdominal ultrasound shows a few small focal areas of small intestine with slightly increased muscularis to mucosal ratio.

- In the liver, I am seeing two 1.0cm lesions in the deep right liver. The first lesion has multiple small cysts suggestive of biliary cystadenoma or emerging hepatobiliary carcinoma. The second lesion looks bilobed, has an echogenic wall, but shows no obvious communication with the gallbladder, cystic duct or CBD. My primary differentials are cystadenoma, cystic carcinoma, or perhaps abscess but the cat feels good. Any other thoughts on the liver lesions and their relationship to the weight loss if any?

This fits biliary cystadenoma
This fits biliary cystadenoma best. Polycystic liver usually has multiple cysts and often has similar renal and panc lesions and persian history. Abscess would have inflammatory patern around it and this one doesn’t. I dont think this cyst is a clinical player in the history.
Ok, thanks Eric! There are
Ok, thanks Eric! There are no other cystic organs in this cat.
