Evaluation of salivary gland tumors with 99mTc-pertechnetate

Journal Article · · J. Oral Maxillofac. Surg.; (United States)
;

The clinical efficacy of salivary gland scintigraphy was evaluated in 32 histologically proven cases. In benign tumors, except Warthin's tumor, 16 of the 20 cases (80%) appeared as cold lesions. All six cases of Warthin's tumor appeared as hot lesions. In malignant tumors, one case each of mucoepidermoid carcinoma, adenopapillary carcinoma, and adenoid-cystic carcinoma were shown as cold lesions, while squamous cell carcinoma and malignant mixed tumor were delineated as a defect image (no uptake of radionuclide). On stimulation with ascorbic acid, retention of radionuclide within the tumor was noted only in Warthin's tumors, but it was noted at the periphery of the tumors in 21 of the 24 cases (87.5%), which might be due to inflammation and/or compression of the gland by the tumors. Salivary gland scintigraphy provided useful information for the evaluation of the site of the tumor and the function of the salivary gland.
