Pathologic vs. abnormal x-ray and MRI findings in runners

The other day I was talking to a runner who had some abnormal findings on the x-rays.  What we could see was calcification in the Achilles tendon that looked like bone chips.  She wanted to know if she should have surgery to remove the calcification or little bony chips that were inside her Achilles tendon. Now, the interesting part of the story is that the Achilles calcification was discovered from an x-ray where she had a stress fracture in one of the metatarsals....in a completely different part of her foot! The pain she was having when running didn't even come from an Achilles tendon problem.  Today on the Doc On The Run Podcast, we're talking about the difference between pathologic versus abnormal findings on x-rays and MRIs in runners.
