Clinical and MRI findings of adhesive capsulitis
Adhesive capsulitis, commonly called “frozen shoulder,” occurs secondary to fibrotic adhesions with thickening and tightening of the joint capsule. Clinically, it is characterized by shoulder pain, stiffness, and decreased range of motion. MRI will demonstrate thickening of the coracohumeral ligament and joint capsule. These changes appear as mildly increased T2-weighted signal intensity within the rotator cuff interval (hiatus between the subscapularis and supraspinatus tendons) and in the inferior axillary pouch.
