[Ultrasonography in diagnosis of neck tumors]

Tumours of the neck are very important problem of the contemporary otolaryngology. In the study the use of sonography in evaluation of expansions of the neck was studied in 200 patients with histologically proven diagnosis. To carry out a detailed evaluation of the individual character of particular types of tumours, all basic features were analysed using the following criteria: echogenicity, echostructure, separation and contour. In this group developed 159 (78.5%) benign tumours and 41 (21.5%) malignant tumours. Malignant tumours were mainly: cystic or solid-cystic, with irregular contour, thickened separation and high echogenicity. Benign tumours were regular, smooth, with low echogenicity and clear separation.
