Dear OCADERs,
I need help on this case of a 50 YO male who had a knee MRI last year that
was diagnosed as PVNS (first slide, sorry I do not have a T 1).
He had nothing done, and came back yesterday for a follow-up which showed
that the soft tissue lesion is smaller (second slide). My question is,
could PVNS spontaneously regress (depending on the amount of hemorrhage)?
Or shall I reconsider another Dx?
Thank you,

Dear Mattar
May be similar case in some point…
In this case, I wonder the mass bleeded so the mass size decreased.
I also had the same question that PVNS could spontaneously regress.
Let me know if anyone has the answer.
Thank you.
Chung, Hye Won
