CT in diagnosis of parotid diseases

Objective To evaluate the CT value in the diagnosis of parotid diseases. Methods CT findings of 56 cases of parotid diseases proved by operation and pathology were retrospectively reviewed. Results Twelve cases were congenital lesions, 32 benign tumors, 9 malignant tumors and 3 abscesses. All of them were localized and most of them were qualified by CT scanning. It was difficult to differentiate low-grade malignant tumors from benign tumors with CT. Conclusion CT has significant value in localizing and qualifying diagnosis in parotid diseases.
