Abstract:
Objective To study CT value in diagnosis and differential diagnosis of submandibular tumor.Methods The CT features of submandibular tumors proved by pathology in 20 cases were analyzed retrospectively and compared with pathologic findings. Double-blind was used to evaluate the value of CT in differentiating both malignant and benign submandibular tumors. Results Of 20 patients,8 were benign tumors, 6 appeared as homogeneous density and well-defined, 2 appeared as inhomogeneous density and partial ill-defined.12 case were malignant of them, 10 were irregular in shape, 8 were heterogeneous indensity, 7 were ill-defined, 5 were well-defined in shape, 4 were homogeneous indensity. Double-blind indicated that 75% submandibular tumors could be qualified by CT, but could not determine the histological type of tumors. Conclusion CT can differentiate most of malignant submandibular tumors from benign tumors, but can not be used to categorize the histological type of tumors.
