45-year-old female with arm pain, assess for humerus intramedullary lesions The muscles and tendons of the rotator cuff are intact. There is mild increased T2 signal and enhancement within the proximal subscapularis muscle, which may represent a strain. A small joint effusion is noted. The glenoid labrum appears grossly intact. The tendon of the long head of the biceps is normally situated within the bicipital groove. The AC joint is within normal limits.The bone marrow signal is within normal limits without evidence of intramedullary lesion. On postcontrast images there is no abnormal enhancing lesion.
No evidence of intramedullary lesion as clinically questioned. Findings suggestive of a mild strain of the subscapularis muscle.
