19-year-old male experiencing pain in shoulder

The correct diagnosis is pseudosubluxation of the shoulder, which refers to inferior displacement of the humeral head relative to the glenoid by fluid in the joint cavity, either hemarthrosis or lipohemarthrosis. This is not a true dislocation.

The radiograph shows a crescent- shaped, low-density region representing fat layering above blood within the joint space. The humeral head is inferiorly displaced, but not dislocated, due to distension of the joint.
This patient was treated with a sling and ice, with a recommendation for early follow-up with an orthopedist.
