ABSTRACT
Occurrence of variant muscular slips from pectoralis major muscle is rare. In this report, we present a rare case of aberrant muscular slip associated with the pectoralis major muscle which we call costodorsalis. This muscular slip originated from the 6th rib near the costochondral junction and ran along the lower border of pectoralis major muscle. It crossed the axilla from medial to lateral side and merged with the latissimus dorsi muscle. This type of origin and insertion is unique and has not been reported earlier. The knowledge of this muscle variation may be of special importance to the anesthesiologists, physiotherapists and plastic surgeons.
RESUMEN
Es poco frecuente la aparición de variaciones de un fascículo muscular desde el músculo pectoral mayor . En este trabajo, presentamos el caso de un fascículo muscular aberrante asociado con el músculo pectoral mayor que denominamos costodorsal. Este fascículo muscular se originó en la 6 costilla cerca de la unión costocondral y corrió a lo largo del margen inferior del músculo pectoral mayor. Cruzó la axila de medial a lateral y se fusionó con el músculo latísimo del dorso. Este tipo de origen y la inserción es único y no se ha informado anteriormente. El conocimiento de esta variación muscular puede ser de especial importancia para los anestesistas, fisioterapeutas y cirujanos plásticos.
