Twenty patients with neck masses, except thyroid and salivatory tissues were scanned by ultrasound.
In all cases, diagnosis was confirmed surgically and was compared with ultrasonographic findings. There were
three cystic tumors, including thyroglossal cyst, thymic cyst and neurinoma. The remaining 17 were solid,
consisting of non, spesific lymphadenitis, tuberculous lymphadenitis, malignant lymphoma, neurofibroma,
cervical node metastasis and so on.
In cervical lymphnodes, metastases appeared as irregular strong echo with acoustic shadow, while others,
including malignant lymphomas, appeared as low echo level masses with evident surfaces. Three neuro-
fibromas appeared as low echogenicity with micronodular strong echo. Though ultrasonography can charac-
tenze a mass as to its cystic or solid nature, it cannot predict the histological findings. Further experiences
would be helpful in revealing the nature of these lesions.
