title: [Detection of muscle, vein and artery infiltrations of cervical lymphatic metastases].
abstract: In a prospective study, 15 patients with squamous cell carcinomas of head and neck and clinical fixed cervical lymph node metastases were examined to determine the value of computed tomography, magnetic resonance imaging and high resolution real time ultrasonography in preoperative recognition of muscle and vessel infiltration. The preoperative findings were compared with the microscopic results of neck specimens and the operative reports. For each diagnostic method sensitivity, specificity, and effectivity were calculated. Ultrasonography, magnetic resonance imaging and computed tomography can assess muscle infiltrations as well. Metastatic infiltrations of carotid arteries are best recognised by ultrasonography and magnetic resonance imaging. Both methods are more valuable than computed tomography. All methods are unsuccessful in detecting infiltrations of the jugular vein. In conclusion, metastatic infiltrations of surrounding tissue, as described by imaging methods, are rarely confirmed by histological results.
