A coronal oblique T1-weighted magnetic resonance image of the shoulder (2007-5-25) (spin-echo sequence with a repetition time of 626 msec and an echo time of 13 msec) shows a focal low signal area in the medial part of humeral head (A), and a coronal oblique T2-weighted magnetic resonance image of the shoulder (2007-5-25) (spin-echo sequence with a repetition time of 3775 msec and an echo time of 90 msec) shows an irregular low signal band on the corresponding part of humeral head (B).
