Evaluation of parotid gland masses by rectilinear scanning.
Twelve salivary gland scans, done preoperatively for evaluation of parotid masses, included nine cases of Warthin's tumor. In addition to Warthin's tumor showing an accumulation of pertechnetate, increased activity was also present in two cases of mixed tumors. Warthin's tumor may also show decreased activity, with or without a large cystic component. Therefore, the interpretation of preoperative salivary gland scans must be made with caution.
