Abstract

Thirty-one patients with localized parotid masses or diffuse parotid enlargement were studied using high resolution scanners, 5 to 10 mm. sections, and a rapid infusion of intravenous contrast material. Sixteen of eighteen (88%) benign tumors were demonstrated. Two (12%) small papable benign tumors were not detected as they were isodense with the normal parenchyma and less than 2 cm. in diameter. Five malignant tumors were studied and all were well demonstrated by this technique. Eight patients with sialadenitis studied were found to have diffuse enlargement and increased attenuation of the affected gland. However, the C.T. examination failed to provide sufficient information regarding ductal anatomy and did not provide further information to identify the etiology of the inflammatory process. These findings suggest that high resolution C.T. scanning may obviate, in most cases, the need for gland opacification during the C.T. examination (C.T. Sialography). Sialography remains the procedure of choice for evaluation of chronic sialadenitis.
