[Computed tomography and ultrasound: comparison with intraoperative findings of large metastases in the neck (author's transl)].

The evaluation of soft tissue lesions in cases with extensive metastases, in the neck is of great importance. The therapeutic concept will depend upon the size distribution and infiltration of the metastases into the structures of the lateral neck. The limiting factors include the great vessels of the neck, the deep neck muscles, the base of the skull, the mediastinum and the proximal parts of trachea and oesophagus. The timing of therapy (operation, radiation and cytostatic therapy) can be planned according to these factors. Computed tomography and ultrasound provide the information about the soft tissues of the neck. Spread, size and site of infiltration can be fairly estimated as shown in 25 patients which have been operated on.
