Fig. 129-year-old man with shoulder pain. Coronal oblique
T2-wighted image shows infraspinatus cyst with intact infraspinatus tendon.
Patient had supraspinatus tendon tear (not shown). Partial-thickness articular
surface tear of supraspinatus and intact infraspinatus were confirmed at
arthroscopy.
Fig. 2B35-year-old man with shoulder pain. Coronal oblique
fat-suppressed T1-weighted image from MR arthrogram posterior to A
shows delaminating component of tear extending into infraspinatus with intact
infraspinatus tendon. Partial-thickness supraspinatus tendon tear and intact
infraspinatus were confirmed at arthroscopy.
Fig. 3B26-year-old man with shoulder pain. Fat-suppressed
T1-weighted image from MR arthrogram in abducted and externally rotated
position shows partial-thickness articular surface infraspinatus tendon tear
and delaminating component of tear. Cyst appears larger than in A.
Partial-thickness articular surface rotator cuff tendon tear was confirmed at
arthroscopy.
