Fig. 1 —20-year-old man with supraspinatus tendinosis. Oblique coronal fast spin-echo T2-weighted MR image shows supraspinatus tendon has increased signal near its insertion on greater tuberosity (arrow). Cystic changes are incidentally noted in humeral head.
Fig. 2 —20-year-old man with infraspinatus tendinosis. Oblique coronal fast spin-echo T2-weighted MR image shows infraspinatus tendon has increased signal near it insertion on greater tuberosity (arrow). Cystic changes are incidentally noted in humeral head near attachment of infraspinatus tendon.
Fig. 3 —17-year-old girl in abduction external rotation. Fat-suppressed proton density image shows infraspinatus being impinged by posterosuperior glenoid labrum (arrow).
Fig. 4 —20-year-old man with cystic changes in humeral head. Axial fast spin-echo T2-weighted MR image shows cystic changes in posterosuperior humeral head near attachment sites of supraspinatus and infraspinatus tendons (arrow).
