【Abstract】 Objective Toevaluate CT scanning in the diagnosis of parotitis. Materials and Methods CTfindings in 12 cases with pathologically proved parotitis were retrospectively analyzed,and a comparison with pathologic findings was made. Results In 7cases, the parotid glands were bilateral diffusely-enlarged with slightly high density.Five cases showed soft tissue mass in unilateral parotid gland. The mass was ill-marginated with heterogeneous density in 3, and localized ill-marginated withhomogeneous density in 2. The parotid gland decreased in size in one case. On surgery nomass was found in all 12 patients. Conclusion For most instances, CTimages allows a confident diagnosis of parotitis to be made.
