This narrative review covers the broad anatomical spectrum of shoulder overuse injuries, including rotator cuff disorders, impingement syndromes, labral and capsular abnormalities, biceps tendon pathology, bursal disease, and osseous and physeal injuries. Imaging alone is not always sufficient for diagnosis because many findings, especially in the rotator cuff, may also be present in asymptomatic individuals. Therefore, imaging should be interpreted in the context of the patient's clinical presentation and biomechanical factors. Magnetic resonance imaging remains central for structural assessment, whereas dynamic ultrasonography adds real-time functional information.

Our case describes a rare etiology given the occurrence after vaccination in a child. Indeed, to date, only two cases of myositis ossificans circumscripta after COVID-19 vaccination have been reported, both in adults. In this first pediatric case, radiographs performed at appropriate time allowed for a conclusive tissue characterization and hence diagnosis. CT and MR scans performed early after clinical manifestation showed only progressive, severe edema of the soft tissue of the shoulder while the later acquired radiograph and radiographic follow-up demonstrated the heterotopic ossification in the deltoid. Rapid soft tissue swelling and edema, in correlation with a potential local traumatic event, even if atypical, should raise suspicion of myositis ossificans circumscripta.

The most common overuse injuries in children include stress fractures, traction apophysitis, and repetitive physeal injuries.
