| Popis: | In children ultrasound is the best tool we have to evaluate any change in the neck, high resolution ultrasound allows excellent details of the anatomy, it´s possible to asses vessels, muscles and glands as the thyroid gland, Which begins it´s formation 24 days after fecundation, it begins at the floor of the larynx and migrates through the thyroglossal duct, by the 7 th week it completes this process, and starts functioning during the 3rd month of intrauterine life, this knowledge of the embryology of the gland is important due to the fact that in the evaluation of the neck ultrasound will allow to differentiate congenital abnormalities that will behave like a mass But it´s not only enlargement or presence of mass the reason to explore the pediatric neck, some patients under the suspicion of endocrinological disfunction, will use it to confirm the suspicion of pathology of the thyroid or absence of thyroid tissue. Wtih Doppler we are able to assess the vascularity of the gland in general to orientate possible diagnosis, or in case of focal abnormality to asses its vascularity. In the thyroid will see benign cyst with the same ultrasound appearance in any other part of the body, isolated or as part of other pathology of the gland. Malignancy is rare but we must be aware of it because when present it´s very aggressive. In children between the age of 4 and 8 the most common cause of mass in the neck, is lymph node enlargement secondary to viral or infectious process, with ultrasound we are able to confirm the etiology of the abnormality as well as do follow up until resolution, or if necessary guide a fine needle aspiration or biopsy Among other pathology we have in the neck, are those related to that of the sternocleidomastoid muscle congenital or acquired. Vascular lesions such as the hemangioma, or masses which have its origin in the fatty tissue such as lipomas, are very well defined by ultrasound. The aid of Doppler to let us know not only the relationship to vessels but to know if it´s a vascular mass or not. |
