My 9 year old Potcake (probably shepherd/lab/etc mix) has a long history of lipomas, which grow fairly large. In late October of 2022 I found a lemon sized mass on the back of his right hind leg, which was not bothering him but was firm. Our vet in Ottawa ON is a VCA practice nearby; I was able to get an appointment the next day. The vet and I were both concerned at the location, size and consistency of the mass.

She recommended an xray of the limb and a chest xray to rule out cancer and metastasis as well as blood work. (all normal) She sedated him for the radiorgraphs and aspirated the mass multiple times with a presumptive diagnosis of lipoma. We discussed the fact that it was probably and inter-muscular lipoma, between the two muscles of the hind leg at the back . To remove it she advised a board certified surgeon elsewhere, who she said would want to do an MRI of the limb first to evaluate the extent of the mass in preparation for surgery. When I expressed concern about the cost she offered a surgeon at the VCA who is not board certified but who may be able to attempt a surgery without the MRI.

Since October the mass has grown, especially medially, and is now the size of a grapefruit. He is still not lame or uncomfortable when I feel the mass. I want to prevent problems for him with this leg but I also worry about the invasiveness of the surgery – and the cost, which I can’t afford right now. I am waiting and watching at this time. I worry about having the mass return even after surgery and wonder about removing the majority of it just to give him more comfort when moving – is it ok to wait until it gets bigger? I know that lipomas don’t tend to spread to other parts of the body like malignant cancer – this is why we took the xrays, to look for other signs of cancer in his body. Now i wonder if this was too soon, and should have waited on those tests.
