Figure 1. A and b. Ultrasound of both shoulders in a 43 year old female patient with unilateral subacromial pain syndrome.
Right shoulder (symptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Intact rotator cuff. The supraspinatus tendon shows a slightly increased width and a somewhat irregular structure as in tendinosis. Minimal neovascularity. Increased fluid content in the subdeltoid bursa. No pathological findings of the acromio-clavicular joint. An area filled with fluid is found within the muscle belly of the infraspinatus, ganglion? Left shoulder (asymptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Within the middle superficial circumference of the infraspinatus tendon, a probable partial rupture is found. No pathological findings of the acromio-clavicular joint. Both muscle bellies of the supraspinatus and infraspinatus are well-developed.
Figure 2. A and b. Ultrasound of both shoulders in a 48 year old female patient with unilateral subacromial pain syndrome.
Right shoulder (symptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Around the tendon there is a small increase in fluid content just below the sulcus like in synovitis. The supraspinatus tendon shows an increased width and hypo echogenic areas similar to in tendinosis. No neovascularity. In the superior distal part of the subscapularis tendon there might be a partial rupture. Some increased content of fluid in the subdeltoid bursa. High echogenic changes like in calcification or osteophytes are present in the acromio-clavicular joint. Both muscle bellies of the supraspinatus and infraspinatus are well-developed. Negative abduction test. Left shoulder (asymptomatic). Intact the rotator cuff. The supraspinatus tendon has an increased width and hypo echogenic areas similar to those in tendinosis. No neovascularity. Some increased content of fluid in the subdeltoid bursa. No pathological findings were present in the acromio-clavicular joint. Negative abduction test
Figure 3. A and b. Ultrasound of both shoulders in a 33 year old male patient with unilateral subacromial pain syndrome.
Right shoulder (asymptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Intact rotator cuff. No neovascularity. Some swelling is present in the subdeltoid/subacromial bursae. No pathological findings of the acromio-clavicular joint were seen from a superficial view. Both muscle bellies of the supraspinatus and infraspinatus are well developed. Left shoulder (symptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Intact rotator cuff. No neovascularity. Some swelling is present in the subdeltoid/subacromial bursae. No pathological findings of the acromio-clavicular joint were seen from a superficial view. Both muscle bellies of the supraspinatus and infraspinatus are well-developed.
Figure 4. A and b. Ultrasound of both shoulders in a 42 year old male patient with unilateral subacromial pain syndrome.
Right shoulder (symptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. There are signs of a small earlier partial rupture within the anterior deep circumference of the supraspinatus tendon at the insertion of the tuberculum majus. A few small minimal calcifications are also seen here. The tendon has an increased width and hypo echogenic areas with moderate neovascularity similar to in tendinosis. Intact rotator cuff. Some increased the content of fluid in the subdeltoid bursa. No pathological findings of the acromio-clavicular joint were seen from a superficial view. Both muscle bellies of the supraspinatus and infraspinatus are well-developed. Negative abduction test. Left shoulder (asymptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Intact rotator cuff. The supraspinatus tendon presents with increased width and hypo-echogenic areas similar to those in tendinosis. Minimal neovascularity at the insertion of tuberculum majus. Some increased the content of fluid in the subdeltoid bursa. No neovascularity. Some swelling is present in the subdeltoid/subacromial bursae. No pathological findings of the acromio-clavicular joint were seen from a superficial point of view. Both muscle bellies of the supraspinatus and infraspinatus are well-developed. Negative abduction test.
Figure 5. A and b. Ultrasound of both shoulders in a 53 year old male patient with unilateral subacromial pain syndrome.
Right shoulder (symptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Around the tendon there is a somewhat increase content of fluid just below the sulcus, which may be a sign of peritendinitis or synovitis. Intact the rotator cuff. No neovascularity. Increased content of fluid in the subdeltoid bursa. The joint capsule of the acromio-clavicular joint is somewhat curved. Both muscle bellies of the supraspinatus and infraspinatus are well-developed. Negative abduction test. Left shoulder (asymptomatic). No pathological findings of the long biceps tendon, which is correctly positioned in its sulcus. Around the tendon there is a somewhat increased content of fluid just below the sulcus, which might be a sign of peritendinitis or synovitis. Intact rotator cuff. No neovascularity. Some increased the content of fluid in the subdeltoid bursa. No pathological findings were seen in the acromio-clavicular joint. Both muscle bellies of the supraspinatus and infraspinatus are well-developed. Negative abduction test. A = acromion, CH = caput humeri, B = bursa, D = deltoideus muscle, SSP = supraspinatus tendon.
