This syndrome should be clearly differentiated from the classical (external) impingement that is thought to be caused by compression of the subacromial bursa, long head of the biceps tendon and rotator cuff (RC) by the coraco-acromial arch. Patient Data Age: 25 years Gender: Male MRI Axial Gradient Echo Axial T1 Coronal T2 Sagittal T1 Sagittal STIR MRI Axial Gradient Echo An os trigonum is seen with alteration of its marrow signal, being of low T1 and high T2 / STIR (bone marrow edema/contusion), as well as surrounding soft tissue edema signal.
