This is completely incidental in someone for Hip MakoPlasty pre op CT….no
such changes at the hip. The Sag is most striking.
I’ve put arrows and masked what I’m seeing so you can hallucinate along
with me.
I feel like we’ve seen this before ….. just can’t remember what we called
it. Do you?
Epiphyseal ghost?

Everyone was so helpful and promptly responsive, thank you for refreshing
my memory!
I have no prior history for this patient…but the axial images included
both knees and the hips (this was Makoplasty for pre-op THR), and there
were no similar findings in the other knee or either hip.
Jon Treasley shared the following:

Which was echoed by Mark Velleman and Pierre Le Hir who pointed out that it
results from immobilisation in childhood.

I think this is epiphyseal growth recovery line.
One can assume there was some event in this patient’s early childhood that
produced recovery/growth lines. As opposed to the example in the article
(see link above) where the patient was a teenager, in your case there were
several additional decades of life that made those lines fade more.

PS…regarding the lobulated intra-articular mass posteriorly in the knee
of a 16M that I recently shared (on June 3rd), the consensus of the very
few who responded was that they didn’t know what it was. Feeling a bit at
a loss, I recommended contrast….I will reach out to the referrer and hope
to get follow up.
