Two Cases of Spontaneous Recurrent Hemarthrosis of the Shoulder with Acromial Erosion Associated with Impingement Syndrome

<div>Oblique coronal magnetic resonance images of the left shoulder. (a) T1-weighted images. (b) T2-weighted images. An extensive hematoma was seen in the glenohumeral joint and the subacromial and subdeltoid bursas, which was shown as low signal intensity in T1-weighted images and high signal intensity in T2-weighted images. Bony erosion on the undersurface of the acromion was detected (white arrows).</div>
