Eosinophilic sialodochitis in the right PG. The parenchyma is hypoechoic and characterized by multiple anechoic formations within the parenchyma corresponding to multiple dilations of Stensen’s duct, giving it a “leopard-skin” appearance. These are oriented along the course of the duct and do not typically have a rounded shape as in sialectatic sialadenitis and are not perfused. Abbreviations: PG, parotid gland; M, mandible; MM, masseter muscle; SD, Stensen’s duct.
