Purpose: The purpose of this study was to describe the sonographic (US) features of parotid gland involvement in patients with sarcoidosis.
Methods: The US findings of the parotid gland of 6 patients with histologically proven sarcoidosis of the parotid gland were reviewed.
Results: The sonographic features ranged from nodal enlargement to diffuse or partial involvement of the parotid gland with various degrees of echogenicity and vascularity.
Conclusions: Because of the lack of specificity of US findings in sarcoidosis involvement of the parotid gland, sarcoidosis should be considered in the differential diagnosis of parotid gland lesions in the proper clinical setting.
