Hi Diane.

Do you have any pictures to share of these areas of swelling?

Any x-rays taken thus far to see what they might be?

Expert:  PitRottMommy replied 1 year ago.

It's hard to tell what is going on in this area. It looks like this is under the skin, is that correct?

Can you attach a photo that shows where the swelling is (you pointing, perhaps) and a whole picture of Maddie? It's difficult to tell what and where the swelling may be.

Has a fine needle aspirate been obtained of this area yet? Just oral meds? If just oral meds, any improvement?

Thanks for the additional information.

Given her age and the location, I would be curious to know if this is a lipoma or a 'benign fatty tumor'. They often appear very well defined (think softball cut in half and laid against the skin). However, other times they are more diffuse in appearance with softer margins. Many of these can soft and fluidy and some of them actually do have fluid surrounding them.

I think your best bet is going to be with the fine needle aspirate of finding what this mass could be. If anything other than fat cells are found, your vet may want to send the sample off for an out-house cytology. If this is a lipoma, chances are monitoring is all that will be needed unless the area begins to cause her undue problems with motion. Most of these reach a certain size and stabilize but they can also become quite large with time. Sometimes surgery is needed, sometimes its not. If this is a lipoma, given its location, I doubt surgical intervention would be needed unless it grew to a much larger size.
