[Sonography of the salivary glands].
358 sonographic studies of the salivary glands of 255 patients with proven diagnoses were evaluated retrospectively. Sonography proves to be highly valuable to differentiate between peri- and intraglandular lesions (98%). Superficial neoplasms can be delineated easily. A sharp margin of the tumour is not reliable to predict benignity, therefore biopsy should be performed in all neoplasms of the glands. Deep infiltrating processes require further evaluation by CT or MR. In cases with sialolithiasis the stones can be demonstrated in approx. 2/3 by ultrasound. Inflammatory diseases of the salivary glands have variant sonographic features. Acute infections usually have hypoechogenic parenchyma, chronic inflammations are more likely hyperechogenic.
