[High-resolution real-time sonography in salivary gland diseases. II: Salivary gland tumors].

74 non-selected patients with suspected tumors of the major salivary glands were examined by high-resolution real-time sonography (7 MHz). The different tumors presented with characteristic but nonspecific echomorphological features. Cysts of the salivary glands, intraglandular lymphadenitis, and paraglandular lesions can be distinguished from real tumors of the salivary glands. In case of uncertain palpatory findings the demonstration of an intact echographic texture pattern proves the absence of a tumor. No false negative ultrasound tumor diagnoses were encountered (sensitivity 100%). In salivary-gland neoplasms high-resolution real-time sonography completes the clinical findings and provides important informations about size, number and type of space occupying lesions.
