title: Radiological findings of adenolymphoma (Warthin's tumor).
abstract: The radiological findings of adenolymphomas (Warthin's tumor) treated in six hospitals between 1985 and 1994 were compared with the operative and histological findings and the usefulness of the radiological examinations was evaluated. The total number of patients was 72. The mean age was 61.8 years; 61 were males and 11 were females. All tumors developed in the parotid gland. Tc-99m-pertechnetate salivary gland scanning was performed in 13 patients and an increased uptake of the isotope was observed in only six patients. Even if Tc-99m-pertechnetate salivary gland scanning does not reveal intense accumulation, this tumor should not be ruled out. By computed tomography (CT), ultrasonography (US), and magnetic resonance imaging (MRI), the margin of all tumors was evident; however, the contents of the tumor varied. The contents and multiplicity of the tumors were well demonstrated by MRI, which was found to be the most accurate imaging modality.
