– 13 year MN DSH (my receptionist’s cat) history of unexplained weight loss
– otherwise asymptomatic; bloodwork, urine unremarkable – resorptive lesion that requires tooth extraction
– approx 4x6cm hypoechoic/mixed echogenic mass in left liver possibly only involving one lobe
– rest of liver looks normal as well as rest of scan (no effusion, lymphdenopathy)
– u/s guided FNA not overly helpful but ruled out lymphoma and mast cell
– mass was quite firm upon needle placement

– looks like something that can be removed but we would like to know what it is prior to surgery so planning on core biopsy
18 gauge or 16 gauge core reccommended? Possible differentials? (biliary adenoma, adenocarcinoma, other?)
Comments
Agree that a core biopsy is
Agree that a core biopsy is needed. Is the blood work and thoracic radiographs normal?
Another differential would be a hepatoma.

Bloodwork normal and three
Bloodwork normal and three view chest rads normal. You can see the liver mass on x-ray.

For surgical resection
For surgical resection views you need to get right intercostal and left intercotsal views wiht subxyphoid long axis views of the pv cbd cvc and ao to ensure they are all clear.
Go to the basic search and type in “resectable liver” and you will see what I mean and the views to obtain to decide if a liver mass is resectable or not.

Solid liver masses in cats are usually carcinomas. cats tend to have to live a long time to have benign dsolid nodules or tumors. Cystic benign tumors are frequent but not solid ones that destroy architecture and cause capsular expansion like this one. IOf its solid you may get a better fna sample wiht a sewing machine approach with a corkscrew technique. you may not have the variety on the slide for the dx.

Here’s an update:
The entire
Here’s an update:
The entire left lateral liver lobe was removed. Pre-surgical u/s guided core biopsy was successful but pathologist is scratching her head. Possible fibrosarcoma? Have sent away sections of the mass to see if we can determine what this was more definitively. So far, the patient is doing well.

Thanks – keep us updated with the HP results.
Final diagnosis: Hepatic
Final diagnosis: Hepatic Fibrosarcoma. Margins appear clean
Pathologist has no references on a primary hepatic fibrosracoma in the cat. There is no evidence in this patient, that we can find, that this is a metastatic lesion.

Hmm paper worthy….Nice

The Fibrosarcoma explains why the fna was not diagnostic. Fibrosarcs need core bx for the dx.
