I think an atypical lipoma with focal areas of fat necrosis should be among the differentials. Any trauma in the history? Deep growing quite large fatty lesion – I think surgical removal of the mass will bring the diagnosis.

I was inclined to report this as a parosteal lipoma, but cases I have seen and have seen reported all have an osseous pedicle arising from the surface of bone. This looks a bit different.
I wonder if it is an osteolipoma (if you think that is a different entity), I found a case report.
What do you think?

There has been a fair amount of growth in this forum, largely from engagement through the LinkedIn OCAD page that launched 2-3 months ago. It is a very internationally diverse group, which is wonderful….welcome to everyone who has recently joined us! FYI, at this moment, we are 1627 users in the OCAD listserv. —Everyone should take advantage of this network to share interesting cases and invite diagnostic assistance or pose important questions. That’s what it is here for.
For those of you who haven’t as yet, check out the OCAD LinkedIn page
….it’s not as "real time" interactive as this web-based forum, but we post cases and use the poll feature to create quizzes, in a never-ending mission to make learning MSK radiology fun
HAPPY NEW YEAR !
