Shoulder pain, cyst The examination is significantly limited by motion artifact.ROTATOR CUFF: There is a full-thickness tear of the distal anterior fibers of the supraspinatus. This is superimposed upon diffuse tendinopathy of the supra and infraspinatus tendons. The teres minor tendon is intact. There is mild tendinopathy of the superior fibers of the subscapularis although there is no evidence of full-thickness tear.SUPRASPINATUS OUTLET: Severe osteoarthritis affects the acromioclavicular joint. A large multiseptated cystic lesion is seen arising from the acromioclavicular joint which is significantly increased from the prior exam. The mass measures approximately 3.7 x 3.1 cm in the greatest craniocaudal and transverse dimensions. Following gadolinium administration, there is no central or solid enhancement. A small amount of fluid containing a calcified body is noted within the subacromial recess.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritis affects the glenohumeral joint. There is degenerative tearing of the anterior and superior labrum.BICEPS TENDON: Evaluation of the biceps tendon is markedly limited due to motion artifact however the intra-articular portion is not well seen which may relate to partial tearing.
1. Markedly limited exam due to motion artifact.2. Cystic mass arising from the acromioclavicular joint likely represents a degenerative cyst (Geyser phenomenon).3. Small full-thickness tear of the supraspinatus tendon with other findings described.
