Previous studies have highlighted the contribution of the anterior serratus
and trapezius muscles given their motor and stabilizing contributions on the scapula (2,19).
Noncontrast CT demonstrated the presence of soft-tissue masses in the infrascapular region bilaterally, just deep to the anterior serratus
and latissimus dorsi muscles, larger on the right measuing 7.1 cm in the AP dimension by 2.5 cm in the transverse dimension, by 6.6 cm in the craniocaudal dimension.
The pectoralis major muscle was under-developed but the pectoralis minor muscle as well as the anterior serratus
muscle were present (Figure-2).
