Kimura's disease with bilateral auricular masses

We report an unusual case of Kimura's disease. An 81-year-old Japanese woma n was shown to have bilateral auricular masses that had begun to enlarge 6 years before, On CT scans, slightly high-density masses with faint contrast enhancement were seen, The masses were heterogeneous and hypointense on T1 -weighted MR images, were slightly hyperintense on T2-weighted MR images, a nd showed heterogeneous enhancement after the administration of contrast ma terial, Kimura's disease should be included in the differential diagnosis o f bilateral auricular tumors.
