[The diagnostic potentials of color-coded Doppler sonography in space-occupying lesions in the head-neck area].

In our experience, B-mode sonography proved to be a valuable method in diagnosis of tumours in the head and neck region. Especially in diagnosis of space-occupying lesions in children we consider it as method of choice. A case report illustrates the efficiency of angiodynography in providing further information about vascular malformations in the floor of the mouth with regard to dignity and extension of the space occupying lesion. Tumourous infiltration of vessel walls by malignant tumours or metastatic lymph nodes and hemodynamic consequences of these pathologic processes in anatomic neighbourhood to these vessels can be visualized. In our short period of experience, angiodynography seems to be a quick non-invasive and non-ionizing imaging technique which is very suitable in evaluation of vascular lesions in the floor of the mouth and tongue region.
