Abstract

During 1983.3.- 1986.8, CT findings of 35 cases of parotid lesions were retrospectively reviewed together with their surgical and histologic findings to determine its value in 3 points. 1) Anatomical localization of the lesion 2) Differentiation between benign and malignant tumors 3) The relationship with the facial nerve And alsoCT Sialography was done in 4 cases. The results were as follows. 1) The age distribution was 1 month-66 years ofage. Male to female ratio was 4:3. 2) The most common benign tumor was pleomorphic adenoma(15%) and the mostcommon malignant tumor was carcinoma(15%). 3) Anatomical localization was possible in all cases by noticing thedirection toward the fat plane was displaced. 4) Invasion to facial nerve was determined by obliteration of the normal "bull's eye". 5) Malignancy was rather suggested when the lesion shows ill-defined border, necrotic centrallow density, lymphadenopathy, and ductal obstruction without a stone. Most of the diagnostic difficulties were incases of inflammatory mass lesions and sialography was more useful than CT in such cases.
