For cervical ectopic thymus, the differential diagnosis should include additional causes of neck masses. This includes common causes of neck masses in children, including: thyroglossal duct cyst. [6] [10] branchial cleft cyst. [10] dermoid cyst. [10] inflammatory lymphadenitis. [10] salivary gland infection. [10] sternocleidomastoid tumor of ...
A common sign is a neck growth. It may be found at birth, or discovered later in an infant after an upper respiratory tract infection. [8] Cystic hygromas can grow very large and may affect breathing and swallowing. Some symptoms may include a mass or lump in the mouth, neck, cheek, or tongue. It feels like a large, fluid-filled sac.
A neck mass or neck lump is an ambiguous mass found in the neck area. There are many different possible causes, [1] including head and neck cancer [2] and congenital conditions like branchial anomalies and thyroglossal duct cysts. [3]
The cause is usually a developmental abnormality arising in the early prenatal period, typically failure of obliteration of the second, third, and fourth branchial cleft, i.e. failure of fusion of the second branchial arches and epicardial ridge in lower part of the neck. Branchial cleft cysts account for almost 20% of neck masses in children. [1]
Thyroglossal cysts can be defined as an irregular neck mass or a lump which develops from cells and tissues left over after the formation of the thyroid gland during developmental stages. [1] Thyroglossal cysts are the most common cause of midline neck masses and are generally located caudal to (below) the hyoid bone.
Absence of the portal system in a first trimester case associated with hygroma and aorto-umbilical fistula. (A): Transverse plane of the upper abdomen with color Doppler applied, showing umbilical cord insertion, stomach, the prominent hepatic artery and no afferent liver venous perfusion; (B): midsagittal plane reconstructed from a three-dimensional volume acquisition were the crown-rump ...
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.

Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
