“…Recognition of this is very important, as stated before (Fasel et al 1994;Rudisuli 1995;Ginsberg and Eicher 1999;Rosenheimer et al 2000;Shaw and Connor 2004), since the variant may be found in the course of exploratory surgery of the neck, as in the case indicated by O'Sullivan and Kay (1998), or may provoke an alteration in the morphology of the clavicle (Ruíz-Santiago et al 2001).…”

Anatomical relationships of the cleidoatlanticus muscle. Interpretation about its origin

An unusual muscular variation, the cleidoatlanticus muscle, was observed on the right-hand side of the lateral cervical region. The upper third of the muscle was concealed by the sternocleidomastoid muscle. There was a loop of nerves surrounding the muscle, formed by an anastomosis between the transverse cervical nerve and the greater auricular nerve. A fine vascular-nervous pedicle (formed by a small branch from the transverse cervical artery and by a branch from the medial supraclavicular nerve) entered the deep surface of the muscle at the junction of its middle and lower thirds. Taking into account the relationships that presented with the superficial branches of the cervical plexus, we consider that the cleidoatlanticus muscle is derived from the sternocleidomastoid muscle.

“…A similar supernumerary muscular bundle, such as the one lying adjacent to the sternomastoid portion of the SCM on the right side in the current study has been reported previously by Coskun et al (2002). The aberrant SCM anatomy could mimic pathological masses of the lateral neck region on clinical and imaging studies including metastatic disease, or benign tumors such as cyst, glomus tumor, neurofibroma, thrombosed vein, hematoma, familiar sternocleidomastoid tumor of infancy, and hypertrophy of the SCM (Rudisuli, 1995;Ruiz Santiago et al, 2001;Rubinstein et al;Tavill & Wetmore, 1996;Fasel et al).…”

RAIKOS, A.; PARASKEVAS, G. K.; TRIARIDIS, S.; KORDALI, P.; PSILLAS, G. & BRAND-SABERI, B.Bilateral supernumerary sternocleidomastoid heads with critical narrowing of the minor and major supraclavicular fossae: clinical and surgical implications. Int. J. Morphol., 30(3):927-933, 2012. SUMMARY:Anatomical variations of the sternocleidomastoid muscle are rare and concern its origin, insertion, and the number of heads. We report on a rare bilateral variant of the sternocleidomastoid muscle with aberrant and supernumerary muscular heads, observed in a cadaveric subject. On the right side of the neck, a typical sternomastoid head of the sternocleidomastoid muscle, and three aberrant clavicular heads of variable thickness, origin, and termination were noticed. On the left side, two sternomastoid heads were present; the medial one was of typical pattern, while the lateral was supernumerary. The cleidomastoid portion of the left sternocleidomastoid muscle was fused with the double sternomastoid segment. A strap-like muscle originating from the middle third of the clavicle and inserting onto the transverse process of the C3 vertebra was noticed. This is known as the cleidocervical muscle. On the right side of the neck, the posterior cervical triangle was diminished, the minor supraclavicular fossa was considerably narrow, whereas on the left, it was diminished in addition to a bilateral shortening of the major supraclavicular fossa minimizing space needed for potential surgical access. These findings are of prominent significance for anesthetists in ultrasound guided needle positioning in brachial plexus block, as well as in subclavian or external jugular vein catheterization, and in surgical interventions involving structures lying under the sternocleidomastoid muscle.

“…Although this particular levator claviculae did not appear to have any clinical significance, it may. It has been mistaken for lymphadenopathy (Rosenheimer et al, 2000), has presented as a tender mass (Ginsberg and Eicher, 1999), and may cause angular deformity of the clavicle (Santiago et al, 2001). Knowledge of its benign existence should reduce the need for unnecessary diagnostic procedures.…”

Levator claviculae muscle presenting as a hard clavicular mass: imaging study

Abstract: We report a case of levator claviculae muscle presenting clinically as a hard mass in the clavicular area due to angular deformity of this bone. To our knowledge, this is the first report where the anomalous muscle shows this clinical presentation.
