At physical examination, bruises were noted along with loss of pectoralis major contour (Figure 1(a)). Magnetic resonance imaging (MRI) confirmed a complete rupture of the clavicular head, pectoralis major insertion with mild retraction (Figure 1(b)).

(a) The right shoulder presented with loss of axilla fold with no bruises due to chronic presentation. (b) T2-weighted images of MRI showed complete torn of pectoralis major muscle in the osteotendinous insertion with retraction up to the medial border of the anterior margin of the deltoid muscle.

On serial examinations, the anterior axillary fold was obliterated (Figure 3(a)). Weakness persisted for another 3 months which necessitate MRI concluding pectoralis major rupture with retraction to the medial border of the deltoid muscle (Figure 3(b)).
