UNASSIGNED: Objective @entity16490 ( @entity16490 ) is a rare abnormality of the thyroid gland and the true prevalence and importance is not known. The aim of this study was to evaluate ultrasonography (US) guided @entity400 ( @entity400 ) results, sonographic features, and frequency of @entity16490 detected in the midline of the neck.Subjects and methods Five thousand five hundred and twenty outpatients who were referred to our thyroid clinic between September 2010 and April 2012 and underwent thyroid US, were retrospectively analyzed. @entity1 with @entity16490 , detected in the midline of the neck in US were included in the study. Thyroid functions, sonographic features, and US guided @entity400 results were evaluated.Results There were 81 (81.8%) female and 18 (18.2%) male @entity1 with a mean age of 50.9    11.7. The @entity16490 in the midline was present in 1.79% (99/5,520) of the @entity1 . In the majority of the @entity1 , benign sonographic features (isoechoic, regular margin, type 1 vascularization) were detected. There were 92 (92.9%) @entity1 with a previous history of thyroidectomy and all were histopathologically benign. In 7 (7.1%) @entity1 , there was no history of thyroid operation. @entity400 results of @entity16490 were benign.Conclusion This study evaluated the importance of @entity16490 detected incidentally in the midline of the neck. Especially in @entity1 with a history of thyroidectomy, the thyroid masses in the midline of the neck can be found as incidental with imaging methods. Our results suggests that the incidence of @entity5 in this group is much lower than orthotopic thyroid nodules and they are often benign.

Importance of XXXX detected in the midline of the neck: single center experience.
