Ultraschalluntersuchung zervikaler Lymphknotenmetastasen: Konzept und Ergebnis einer histopathologischen Aufarbeitung

Our results confirm the reliability of ultrasound regarding sensitivity, specificity and accuracy of US-detectable cervical lymph nodes as reported in world literature. However, we were able to demonstrate in special histopathological explorations, that ultrasound did not detect more than 50% of present lymph node metastases in our series. We consider it essential to perform histopathological explorations of the soft tissue of the neck as described in our study to evaluate the efficacy and reliability of US, CT, and MRI in detecting lymph node metastases of head and neck malignancies.
