국문 초록

Variant muscles of the cervicobrachial region are relatively uncommon. One rare variant muscle of this region isthe cervicohumeralis, which arises from the cervical vertebrae and inserts onto the humerus. During routing dissection ofthe left neck region, a variant of the cervicohumeralis was identified. Most of the muscle was located in the posterior triangleof the neck but had distal attachments onto the corocoid process of the scapula and the lesser tubercle of the humerus. Suchvariant muscles are important to consider during image interpretation or surgical procedures in the neck and proximal upperlimb. To our knowledge, this is the first case report of an additional attachment of the cervicohumeralis onto the scapula. This variant might be called the cervicoscapulohumeralis muscle and should be distinguished from other muscle variants inthis region on medical imaging.
