【 摘 要 】

Bilateral variation in origin of pectoralis minor is not reported commonly. Higher origin would likely to restrict the movement of shoulder especially abduction and lateral rotation. Origin of pectoralis minor from 2nd to 4th ribs and costochondral junction is recognized in 15% cases. This could press on excessive stretch to the neurovascular structures, thereby giving rise to neurological and vascular symptoms in the arm. This case report is demonstrating need for continued reporting of anatomical variation and ongoing discussion of their functional and clinical significance.
