Investigation with CT has been performed on 20 cases of parotid gland tumors. The intravenous contrast enhancement method was performed in all cases. Six cases were examined by CT and simultaneous sialography.The results were as follows:1) If and when the margin of the tumor was indistinct and irregular, malignancy was suspected. However, it was difficult to diagnose malignancy by CT examination only.2) CT for parotid gland tumor was effective in identifying invasion of tumor into the parapharyngeal space and intracranial space.3) CT with simultaneous sialography was very effective in locating the parotid gland tumor.4) CT of axial sections for parotid gland tumor was more reliable if coronaly sections are taken together.5) CT of malignant and benign tumors were diffusely enhanced by the intravenous contrast enhancement method. However, this was not an indispensable method.
