Sternomastoid Tumor: causes, symptoms and treatment

Sternomastoid Tumor is a small, painless, noncancerous swelling in the lower half of the sternocleidomastoid muscle that appears in newborns a few days after birth. In this article we will look at the causes of the Sternocleidomastoid tumor, its symptoms and treatment methods.

Causes of Sternocleidomastoid tumor

A Sternocleidomastoid tumor is formed when the fetal neck is in an abnormal position in the uterus, which affects the blood supply to the affected muscle. Most often, this tumor occurs when the fetus is breech in the uterus during childbirth. This factor leads to a decrease in blood flow in the sternocleidomastoid muscle and, ultimately, to the formation of a tumor.

Symptoms of a tumor of the Sternocleidomastoid

A tumor of the Sternocleidomastoid can lead to a slight tilt of the head towards the tumor and a turn of the face in the opposite direction. The child may also experience uneven development of the muscles of the neck and shoulder girdle. In some cases, the tumor may be accompanied by limited mobility in the neck.

Treatment of Sternocleidomastoid tumor

Treatment for a Sternocleidomastoid tumor usually begins with physical therapy, which helps improve all body movements. However, in this case, the neck is not stretched. Massage and exercises for the muscles of the neck and shoulder girdle may also be prescribed.

In some cases, surgery may be required, especially if the tumor is large or causing discomfort to the child. Surgery may involve removing the tumor or just part of it.

In conclusion, Sternomastoid Tumor is a small, painless, noncancerous swelling that appears in newborns. Treatment includes physical therapy, massage and exercises for the neck and shoulder muscles, and in some cases surgery may be required. Parents should consult a doctor if their child develops the symptoms described above to receive recommendations for the diagnosis and treatment of a sternocleidomastoid tumor. Seeing a doctor early will help speed up the healing process and reduce the risk of possible complications.



A tumor of the sternoclavicular muscle in a child is a small, painless formation that appears after a few days of life. This tumor is typical of newborns and is caused by improper positioning of the fetal head in the womb. Usually the tumor goes away on its own within 1-2 weeks without any treatment. However, in later stages of this, secondary problems such as head tilt and changes in neck muscle function may occur. These changes can be corrected with physical therapy, which improves mobility and helps the child develop normally. From a treatment point of view, it is important to identify the tumor as early as possible - this will avoid complications and
