This goal of this study was to retrospectively characterize the MRI features of a series benign crystalloid-containing parotid cysts. A total of 4 patients with fine needle aspiration findings of crystalloids and available parotid MRI scans were identified. Review of the imaging revealed that the cystic lesions contain layering material that corresponds to crystals. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
