Bilateral sternalis muscle in a Sudanese cadaver

Sternalis/rectus sterni is a rare muscle found in the anterior chest wall, it occurs in 35% of humans. The early detection of its presence is critical in regular mammogram screening in order to avoid possible differential diagnostic dilemma. We report here a case of the sternalis muscle observed bil...

Description
Summary:	Sternalis/rectus sterni is a rare muscle found in the anterior chest wall, it occurs in 35% of humans. The early detection of its presence is critical in regular mammogram screening in order to avoid possible differential diagnostic dilemma. We report here a case of the sternalis muscle observed bilaterally, it was found during routine dissection session of an elderly male cadaver in the dissection room, Faculty of Medicine, University of Khartoum. Sternalis muscle is a familiar entity to anatomists, but can pose a diagnostic and surgical dilemma to some clinicians. Presence of the muscle can be confusing in regular mammogram screening and CT and MRI should be utilized to clear the dilemma, and further evidence needs to be explored and studied. •Sternalis/rectus sterni is a rare muscle found in the anterior chest wall, it occurs in 3-5% of humans.•We report here a case of the sternalis muscle observed bilaterally, it was found during a routine dissection session of an elderly male cadaver in the dissection room, Faculty of Medicine, University of Khartoum.•Presence of the muscle can be confusing in regular mammogram screening and CT and MRI should be utilized to clear the dilemma, and further evidence needs to be explored and studied.•Considering its insignificant function, it could be used as a muscle flap in surgical reconstructions of the head, neck, chest wall and breast.
