Parotid Tumors: CT diagnosis

Purpose To evaluate the value of CT diagnosis for parotid tumors. Methods The CT image of parotid tumors conformed by operational pathology were retrospectively analyzed in 50 patients. The correlation between the preoperational CT diagnosis and the retraoperational pathology was studied. Results There were 35 cases benign tumors and 15 case malignant tumors. The benign tumors appeared as homogeneous density and well - defined margin in 33 patients, but heterogeneous density and ill-defined margin in 2 case. The malignant tumor were displayed as the larger diameter, heterogeneous density and ill- defined margin in 15 case. Conclusion CT can find the parotid tumors sensitively, and define the benign and malignant nature, but can not be used to classify the histological type of parotid tumors.
