For answer see page 130 Figure: Axial (A) and coronal (B) T2-weighted fat-suppressed and large-field-of-view coronal short tau inversion recovery (C) magnetic resonance images of the right shoulder. A 41-year-old man presented with moderate right shoulder pain on abduction. He had a history of sudden-onset right shoulder pain (10/10 in intensity) at rest and profound weakness on right shoulder abduction 1.5 years earlier. The pain and weakness remained at the same level for approximately 2 weeks and then gradually improved. At presentation, the patient had pain rated 7/10 in intensity and muscle strength rated 4 out of 5 (5=normal) on right arm abduction, but no pain at rest. Significant atrophy of the deltoid muscle and mild atrophy of the right pectoral muscle were noted, in addition to numbness along the lateral aspect of the right shoulder.
