Aberrant insertions of the pectoralis minor tendon are quite rare. Most cases are incidental findings during cadaver dissections, on an MRI or during surgical procedures of the shoulder joint. Rarely the aberrant insertion points can be a source of pain or restriction of the shoulder joint. From the literature review, we found that there has been no mention regarding the frequency of occurrence of this variation with respect to unilateral or bilateral occurence, and only three cases have been reported, in which aberrant bilateral insertions have been documented of which two were noted during cadaveric dissection and one radiologically. We report a rare case of aberrant bilateral insertions of the pectoralis minor, which was found during an arthroscopic procedure, and we discuss its clinical and surgical implications.
