The authors examined by ultrasonography 120 patients with nodular cervical syndrome. The ultrasonographic diagnosis, due to a high differentiating capacity of contemporary techniques, have a 100% sensitivity as regards detection of node enlargement. In the differential diagnosis of nodal syndromes an important part is played by various criteria such as size, shape, outline and echogenicity of nodes incl. evaluation of hilar structures. High specificity as regards evidence of metastatic affection was obtained from assessment of the L/T quotient (88.8%). A relatively high percentage of patients with secondaries in the nodes had a transverse diameter longer than 9 mm (86.5%). Ultrasonography can be considered in the great majority of cases a satisfactory imaging method for detection of enlarged nodes with a relatively high informative value on their internal structure. Promising results are obtained also from coloured coded duplex sonography.
