Adding two cases from my archive on IFI, illustrating both findings in this region.
1. Adventitial bursitis due to IFI-related chronic tearing and atrophy of the quadratus femoris.
2. Elastofibroma (bx proven, in this case showing a normal ischiofemoral space, but still is an area of friccion).
I believe they are separate entities (but one would not exclude the other).

I add my vote to the adventitial bursa group. As for the elastofibroma story, most of the cases of active scapulothoracic impingement that I see are at the superomedial corner whereas elastofibromas are typically lower down towards the inferomedial corner. This would suggest they are separate entities. Simon

I’ve received a few comments / questions.
George Koulouris said that he has biopsied a much larger similar lesion in this location out of concern for sarcoma that was signed out as Adventitial Bursitis.
Andrew Kingzett Taylor just echoed a vote for adventitial bursitis—so we’re in good company.
There is no named bursa here..so that is what I reported this as.
A fellow shared this case….as it is similar…but in this location, that is Obturator Externus bursitis, which I occasionally see accompanying ischiofemoral impingement.
Here’s a curious question, from Rodrigo Aguiar who shared this article with me (I think, maybe again)…unfortunately it is not open access.
I’m curious what you think about it.
I’m inclined to think it’s much ado about nothing
