Rupture of the Pectoralis Major: A Case Report

Abstract

The rupture of the pectoralis major muscle is a rare entity. It occurs in young, healthy athletes during violent, eccentric contraction of the muscle with the arm held in an abducted and extended position, particularly in weightlifting. Diagnosis of pectoralis major tendon rupture can be made based on clinical examination but imaging plays a crucial role into confirming the diagnosis. Magnetic resonance imaging (MRI) is the most sensitive imaging modality for diagnosing, grading, evaluation and surgical planning of pectoralis major rupture. Early surgical treatment is associated with better outcome. We report a case of rupture of the pectoralis major in a 32-year-old man who presented a rupture of the pectoralis major after weight lifting.
