      January 20, 2015 at 12:45

      By this T1 sag image I couldn’t definitely choose mycoid degeneration of ACL, though it’s the more likely diagnosis. The ligament is swallen, but I’m not sure that it’ s not ruptured. At this picture I don’t see the secondary signs of ACL tear, but I have no other MR pictures (PD, T2 etc.) So, for me, the answer B. is the MORE likely diagnosis, not the most likely.
