Abstract

Anatomical variations or accessory muscles on the neck region are important for clinicians and surgeons. This case report aims to contribute to the literature by demonstrating the presence of a previously unrecognized muscle on the lateral neck region. During routine gross anatomy dissection of a 59-year-old male cadaver; an unreported muscle was observed next to the scalene muscles on the left lateral neck region. The distance between the center of the scalenus medius and the insertion of the muscle was 6.17 cm, and the distance between the scapular notch and the insertion of the muscle was 1.56 cm. The distance between the aponeurosis that connects the superior and the inferior bellies of the omohyoideus muscle and the first head of the muscle was 6.24 cm. This anatomical formation, which is not included in the literature, has anatomical and clinical importance in controversial clinical cases in neck pathologies.
