MRI OF RIGHT SHOULDER
HISTORY: Supraspinatus tendon tear, right shoulder
TECHNIQUE: MRI examination of the shoulder is performed with a local coil.
Transverse, oblique coronal and oblique sagittal short TR/TE and long TR/TE and fast spin
echo images are obtained. Additional axial, oblique coronal PD fat suppressed images are
done.
FINDINGS:
There is a type II acromion [concave inferior border with anterior subacromial spur]. The
acromion process thickness is measured about 6.5 mm. There is no anterior or lateral down
sloping of the acromion process. There is osteoarthritis of the right acromioclavicular joint.
There is subacromial-subdeltoid bursitis.
There is loss of normal muscle bulk with grade I fatty degeneration (fatty streaks) of the right
supraspinatus and subscapularis muscles. There is tendinopathy with complete full-thickness
tear of the right suprspinatus tendon. There is retraction of the SSP tendon underneath to the
AC joint. Tendinopathy with incomplete full-thickness tear of the right infraspinatus at
anterior tendon portion, (measured about 1.2 cm in length* 0.5 cm in width) is present. The
subscapularis and teres minor tendons are intact without evidence of tendinopathy or tear.
On this nonarthrographic examination, the biceps and labrums are normal. Minimal amount
of fluid is present in the shoulder joint. No loose bodies are identified.
There are few small right posterolateral humeral head bone cysts, (measured about 0.2 cm in
diameter).
IMPRESSION:
- Evidence of anterior subacromial spur may contribute external impingement, right
shoulder.
- Tendinopathy with complete full-thickness tear of the right supraspinatus tendon.
(note: retraction of the SSP tendon underneath to the AC joint).
- Tendinopathy with incomplete full-thickness tear of the right infraspinatus at
anterior tendon portion, (about 1.2 cm length* 0.5 cm width).
- Grade I fatty degeneration of the right supraspinatus and subscapularis muscles.
- Osteoarthritis of the right acromioclavicular joint.
- Subacromial-subdeltoid bursitis.
- Few small right posterolateral humeral head bone cysts.
