femoral incidental finding on MRI + pain

Doesn’t look like AVN or stress reaction, too old for FOPE focal periphyseal edema. Can’t R/O infection but awfully long development time. Interested to hear other opinionsJoel Rubenstein

Dear all,

19yo male patient who fell 2 month ago with persistent proximal femur pain and vicious standing, RX and US didn’t show anything so the doctor wanted an MRI.

3 months ago he had an MRI which shown a incidental finding in the metaphysodiaphyseal proximal femur of what looks like an enchondroma, bone rads 1, with less than 1/3 endosteal scallop (not shown here, on axial).

They asked for a control 3 months later (today), and something else appeared in the juxta-physeal subchondral epiphyseal femoral head.

I’m wondering what could appear so fast within 3 months? Would that more likely explain the pain the patient is experiencing? Any idea to what it could be? I have some ideas, but I don’t want to sound alarming.

Best,

David
