Fibromatosis colli (FMC), also termed sternocleidomastoid tumor of infancy, pseudotumor of infancy, [1] and infancy sternocleidomastoid pseudotumor, [2] is an uncommon (incidence: 0.4%–1.3% of live births), congenital tumor in one of the two sternocleidomastoid neck muscles although rare cases have presented with a FMC tumor in both sternocleidomastoid muscles.

The sternocleidomastoid muscle originates from two locations: the manubrium of the sternum and the clavicle. [4] It travels obliquely across the side of the neck and inserts at the mastoid process of the temporal bone of the skull by a thin aponeurosis. [4] [5] The sternocleidomastoid is thick and narrow at its center, and broader and thinner ...
The anterior cervical lymph nodes are a group of nodes found on the anterior part of the neck, in front of the sternocleidomastoid muscle. These can be grouped into a deep and superficial group. The superficial group drain the superficial surfaces of the anterior neck.
Bezold's abscess is an abscess deep to the sternocleidomastoid muscle where pus from mastoiditis erodes through the cortex of the mastoid part of the temporal bone, medial to the attachment of sternocleidomastoid, extends into the infratemporal fossa, and deep to the investing layer of the deep cervical fascia.
The diagnosis of branchial cleft cysts is typically done clinically due to their relatively consistent location in the neck, typically anterior to the sternocleidomastoid muscle. For masses presenting in adulthood , the presumption should be a malignancy until proven otherwise, since carcinomas of the tonsil, tongue base and thyroid may all ...
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.
Muscle or body aches. Headache. Nausea or vomiting. Diarrhea “These variants still have the potential to cause severe disease,” Russo says. Is there a booster shot against the XEC variant?
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
