Just spoke to surgeon on this ischial lesion I sent out a month ago.
His CT-guided bx (done in another state) was inconclusive, showed "bone", but specific markers could not be assayed.
He is planning en bloc resection and will let me know what comes of it, after which I will report back.

so I got a smattering of replies, most of which agreed that this is likely BPOP. 2 people suggested an atypical osteochondroma and one suggested HO. (Both of these were mentioned in the Ddx in my report, but I strongly favored BPOP).
Spoke to the orthopedic oncologist who has bx’d the lesion and is waiting for results…. I’ll send followup when I get it.

42M with hip pain and decreased ROM.
I think this is most likely BPOP (bizarre parosteal osteochondromatous proliferation) /Nora lesion of the acetabulum (which has been reported, but never seen by me….)
Thoughts? It just doesn’t fit for parosteal OGS, osteochondroma, etc.
