Abstract
The muscular axillary arch (pectorodorsalis muscle) is an uncommon muscle variant that extends from the lateral border of the latissimus dorsi to the pectoralis major muscle tendon, crossing the axillary space (Bergman et al. 1984). This muscle has been reported to appear in 5% to 6% of axillae observed in cadavers. Here, we describe the presence of 4 muscular axillary arches in three cadavers (one cadaver presents the muscle bilaterally). These represent 20% of the axillae in the sample of 10 cadavers, a higher percentage than expected. The muscular axillary arch also is an important variant clinically as the muscle can compress the neurovascular bundle of the axilla (Rizk and Harbaugh 2008).
