  Rim-Rent Tear of the Supraspinatus Tendon: The Hidden Rotator Cuff Injury That Shoulder MRI Can Easily Miss Clinical Hook A 54-year-old man presented with persistent right shoulder pain that had gradually worsened over several months. Raising his arm above shoulder level caused sharp pain, nighttime discomfort disrupted sleep, and simple daily activities such as dressing became increasingly difficult. Initial radiographs appeared unremarkable. Even the first MRI interpretation suggested only mild tendinosis without a definite tear. However, a closer review by a musculoskeletal radiologist revealed a tiny focus of high signal intensity at the anterior insertion of the supraspinatus tendon, accompanied by subtle bone marrow edema of the greater tuberosity. The diagnosis? A Rim-Rent Tear. Although measuring only a few millimeters, this lesion explained every clinical symptom and significantly altered patient management. Early recognition prevented progression toward a comp...

Subscapularis Calcific Tendonitis and Myositis: MRI Findings, AI Applications, and Advanced Clinical Management Introduction A 45-year-old woman presents with severe anterior shoulder pain that developed without significant trauma. The pain has progressively worsened over several weeks, frequently waking her at night and limiting daily activities such as dressing, lifting objects, and reaching overhead. This clinical scenario is encountered frequently in orthopedic clinics and radiology departments. However, while many clinicians initially suspect adhesive capsulitis or nonspecific rotator cuff disease, a less common but clinically important diagnosis may be responsible: calcific tendonitis of the subscapularis accompanied by inflammatory myositis. Among all rotator cuff tendons, the supraspinatus is the most common location for calcium hydroxyapatite deposition. Subscapularis involvement is considerably rarer, accounting for approximately 5% of cases, making accurate imaging diagnosis...
